- Will ATF and engine flush bring the compression back? On this episode of daily driving a classic weekly I test a few things to see if the compression in cylinder 2 can be improved. I test soaking in ATF and using engine flush to bring the compression back. Will it work?

Mate I've been laughing for the last minute and a half when you tried to purge the cylinders of ATF
Word for the day: Schadenfreude - pleasure derived from the misfortune of others. Example: choking with laughter when that towel shot up and the ATF went everywhere! Sorry about the mess, but that was a classic "hey watch this" moment. Hope this works out. Saw the instigram post and praying for a speedy delivery for your wife and child.
I'm finding this car experiment very interesting. You're making progress, stick with it Adam
That engine should hang in there for some time to come. It sure runs well.
Great video and keep up the good work!
I audibly went WHOAAA when the rag and fluid shot up
Just drive it, put some more miles on and then check it in a few months. If it does not improve, but still runs well, just use it. If it does improve , then a result.
I will do that John. The idle is slightly uneven under old in gear but otherwise it runs great
That engine has healthy oil pressure. You need more patience with the #2 rings to come back. I would expect it to need one or two thousand miles of driving to un~stick the piston rings on #2.
This are very good to see how well these products work, for yourself and for others, Thank you Adam, I hope this saves the engine. The interior looks great.
Remember the old headrests. Quite an improvement.

Hi Adam, best wishes. I watch all your videos as you put them up. Really enjoy them, being a Jag owner myself. Just wanted to tell you about the really great channel I just found - Ivan's Shed - this guy is 80 years old and an absolute genius with cars. Only a few videos to watch there and every one a classic. You should get some good ideas there. Have a good one.
Team work, it's a 6 cylinders, so even if some are weaker, it might still do the job fine. Interesting to see! My XJ40 did its first start on the ''new'' mazda 3 fuel tank and it runs just fine. The old fuel tank was leaking and too far gone, with no replacement available. This new tank was quite some work to adapt and I still have to do some woodwork and carpeting to hide it properly, while keeping access to it if needed.
Great job getting a tank to fit! It’s too bad that so many parts are not available for the XJ40
Not a bad engine really. I've seen cars with much worse still in use. Interesting to see the results of the very thorough flush though.
"That went everywhere...." 😂 This has meme potential! There is nothing wrong with a little bit slapstick from time to time - anyway: great vid as always. Thanks! PS: I've ordered an "uprated" oil pressure valve for mine and hope that solves my high pressure issue...
Slapstick is great! I always have terrible dad jokes at home
I’d be interested to hear how that new valve goes!
I burst out laughing at this too. It's just too familiar :D
Replace the oil pressure relief valve spring or old bodge, put some filed out washers below it.
I got a 92 xj40 and just got a oil change from Valvoline the other day, and as soon as I pulled off I looked in my rear view mirrors and seen the whole street covered in white smoke 💀
I hope the white smoke stopped for you
Hi! The AJ6 engine is slanted, so some oil get through the exhaust valves, especially if it hasn't run for some time. It will more than likely go away as you are using it. Mine did that too at its first start, but it doesn't anymore.
My XJ40 blows a small amount of blue smoke at first start up if it’s been sitting for a month or so. Goes away as I use it
Really appreciate your videos! I have an 08' Jag VDP which I hope to get back on the road, now the immobiliser is standing in the way :(
in uk we have a product called REDEX an upper cylinder lubricant you can either add to fuel or directly to intake for more active dose.maybe worth a look. i think that engine has many more miles in it .
Ideal compression is 175 psi?
Loss of oil preasure could be the pick up pipe in the sump where it bolts to the block, the gasket comes loose.
Could be the oil preasure transmitter on filter housing giving a low reading.
The pressure relief valve can be removed in position. Remove the the oil filter housing its inside.
A few videos back you found a leak? i.e liquid in the rear carburettor mouth. I have know inlet manifolds go porous. It might be worth taking the inlet manifold off to leak check it. If you have a leak from the manifold and it is dripping in to number 2 cylinder, this could be your problem. The damage the leak has already done is another thing. On the leaking manifold i found, i took it off the car and plugged up one end of the coolant supply, put an air line on the other end and pressurised the coolant passage. I also heated up the manifold and in due course a crack opened up. This was after a long exhaustive search. I wish you
well.
Oh adam,i have to say that haf me laughing my head off.didnt think it would have bin anything like that powerfull.
Glad to see I am not the only one that FERKS up on camera, and I am sure some people only watch to see screw ups, like watching nascar people only watch for the crashes. Your so silly ATF stands for Airborne Transmission Fluid :), I know it's two late now but throwing and old towel over the engine would have reduced the mess.
Adam, can i add another comment ???
...
Where i live there is a large bridge that spans an estuary !!!
...
Even way back as a teenager, we always knew that when the Jaguar 4.2 saloons used to pull up to pay at the toll booth, they ALL pulled away leaving white/blue smoke behind them !!!
...
(a bit like the "top end rattle" on the BMW 6 cylinder engines !!! - they never broke)
(it was just a tolerance built into the engine many years back)
...
HAPPY JAGUAR MOTORING BUDDY !!!
My sons -69 have similar compression problem and we wounder if it is the rings or valves. Did a leakdown test and at least there was som air coming from the crankcase breather. What remains for us to do is to dismantle the in/out manifolds and listen to leakage coming from the valves, but I would appreciate if you do that first so that we can learn by watching.
If you heard it from the crankcase breather it sounds like rings to me
@@LivingWithAClassic It may well be the valves too, curios to know how it sounds
Engine after flush sounds like it is not getting oil to the top of the engine. So if it were not overhead cam I would say it sounds like tappers.
That's good oil pressure
Is this for all engines or just this one in particular?
To the best of my limited knowledge, ATF is the fluid used in automatic gearboxes. ¿Why do you use it to flush the engine? ¿Does it have solvant properties to melt the gunk and carbon buid ups inside the engine?
It has a lot of cleaning products in it to remove sludge and it lubricates very well. It’s a cheap and safe method to remove carbon
@@LivingWithAClassic Good to know. Thank you!!
Interesting !
I find the volume varies quite a lot during the your videos sometimes. I often have to adjust the volume right up to max and then down quite a lot for the next sequence.
Hi Adam !!!
...
Just had a stupid thought !!!
...
I haven't watched the video right through, but if you just removed the plugs, and squirted some release oil into the bores and let the oil lubricate the rings for maybe a few days and then just squirted a splash of 2-stroke... would the compression just balance up after a short run ???
...
Then after a few weeks just change the plugs to prevent misfires ???
...
The engines in the UK just went on forever and all with low oil pressure !!!
...
They just all rusted away eventually !!!
...
Great cars though !!!
Aren't old Jags supposed to smoke if they run? Or is that just the carbs that cause that? 😂 Nice car, though. Try spraying water in the carb while it is running on the mist setting. It will help the rings, valves, and complete combustion chamber to clean itself of carbon. Im being completely serious.
It’s a smoke screen 😉
Check the valve clearances and if good, yank the head off, de-coke and grind the valve seats. I never trust electric oil pressure gauges so install a simple mechanical type. Check that your oil pressure gauge is running off 12V and not the regulated voltage used for fuel and temperature - ask me how I know?
Head gasket just been off and valves have just been ground. The gauge was checked with a mechanical one also in a previous video so it’s pretty accurate within a few psi.
Pretty happy with the oil pressure now. It’s above the minimum required at 3,000 rpm
as lomg as the engine runs without knocking, oil pressure is overrated. Just drive the car some more miles, don`t stress the engine. Next time, instead of expensive engine flush, use diesel. I do it always, on any car, since 1989, all engines are clean inside after a diesel flush. piston ring can come back.
Isn't ATF fluid not bad for your paintwork?
And hope everything goes well in the hospital.
Nah,you're thinking of brake fluid
Of course you could have just used more ATF as the engine flush, or diesel for both....
At least it seems usable for now, and yes I would check the valve clearances on cylinder 2.
At least you don't seem to be steam-cleaning the oil off the cylinder bores any more...
after draining just crank the engine for a second just to blast out the remaining in the pump.
You dont need to throw out nice new oil to flush remainings. Thats not acid, man.
Well it’s cheap parts store oil. Nothing I’d ever run for more than a few minutes in a car
@@LivingWithAClassic Castrol Classic Car oil is more expensive than most synthetic store brand oils.
I will use 20w50 oil in this old engine trust me old engines do not like 10w30 👍
Guess you don’t understand the video. The thin oil is just to flush and nothing else. Perfect for slushing and engine. The you run it on the 20w50
@@LivingWithAClassic I do understand now and good jop 👍
That motor needs a Rebuild.... No Ifs ands or buts. You have a 5 cyl engine at best.
Instant telltale is It's Far too noisy for a Healthy Jaguar 6.
Jaguars are NOT cheap to own.
If you can't afford to maintain it.. Sell it.
Are you a new dad yet Adam
Not yet Vincent. We are at the hospital as we speak. 15 hours of labor pains so far
@@LivingWithAClassic good luck hope all goes well.
@@LivingWithAClassic Good luck!
