911 Carrera 3.2L Engine Gets Some LOVE - SeaFoam Treatment, Leak Down Test, Valve Adjustment
HTML-код
- Опубликовано: 8 сен 2024
- Mac's Carrera engine gets some love and passed a tough health checkup. I did a valve adjustment, removed some old cracked fuel lines, and performed leak down and compression tests. Now I need to decide if I should use the identical engine from the wrecked cabriolet or not. I guess is comes down to price?

Thanks for the video and update. Think it was very smart to get to the lines while engine is out. Nice that you can rebuild the fuel lines with the original fittings. No chinesium there
I agree. Porsche makes them but they include the Porsche tax as well
Thanks for the link to leak down tester. LoL helps to click on Show more. Do'h!
Tom - Sorry to hear about the cabriolet. Let's hope the insurance company makes you whole.
Re: Cleaning the engine with Seafoam. I added a flex-fuel sensor to my EFI conversion (along with compatible fuel lines, injectors, pump, etc), and I have every intention of running E85 on my SC over here in France as it is about half the price at the pump (biggest producer in Europe.) Apparently running E85 has a pretty nice cleaning effect on the engine's pistons, etc.
I've heard that too about e85. Be careful because it will also eat your fuel lines and fuel pump.
@@GarageTimeAutoResto I'm running an ethanol compatible fuel system from front to back. The old system was all rotten (age, corrosion), so when I replaced it I made sure it was up to spec. No half measures! 😉
Hi the valve lash is 4 intake exhaust dead cool engine
Great stuff Tom. Looks like you've got a solid engine there. Sorry to hear your cab was wrecked... was that the red one? That's too bad.
Yes, it's a gonner. Sad
Great video, thanks!
I’ve idled my car in the garage when it was super rich and shit man. I felt so dizzy. May want to run a metal house to outside your garage. Been thinking about this myself.
Hmm, doesn't bother me, but when I ran the seafoam in, I left the building. The big puffs of smoke I didn't even video because it was intense. Air flow in my garage is like being outside especially with a fan on. A metal hose is also a good idea. Even better is to fix the rich engine!
@@GarageTimeAutoResto makes sense. Lol. My garage doesn’t “breath”
I’m always afraid of passing out and dying so I have to remind myself to go out for fresh air once in a while.
Yeah, be safe
besides the idea that the lines would not look 'original' why not upgrade the fuel lines with more modern ones that have an external shield and last longer, more resistant to abrasion and cracking due to the heat cycles?
It's a slippery slope to redo all the fuel lines with PTFE AN hoses. For example the rails, regulators, dampers, are all odd ball metric fittings. I'm going to do motorsport quality lines when the ITB's go on.
Great video Tom! Where did you purchase the leak down gauge set? I can see that is a great test to do alongside the compression test. Two thumbs up on your 3d printed holder. That hose you were putting the Seafoam into...where did it lead? Did you also run the Seafoam through the fuel system?
One side of the hose goes to a vacuum valve. Not sure what it does, but I think it has to do with a charcoal canister purge. Not needed in my car. The other end goes to a port just below the throttle plate. The engine vacuum sucked the seafoam in. I added in short spurts.
I'm using a different fuel injection cleaner in the gas. Gumout brand I think.
Sorry to hear the 964 was wrecked, you didn’t get to enjoy it very long. Hope the insurance covered your loss. Do you plan on getting a new one?
I know, I'll do an update video soon
You should have a stainless flexible fuel line made for the Y line. I did, no future leaks are possible......that Y line should never have been supplied in rubber with those crimps......notorious for leaking. All SS Y line is about the same price as a new OEM line.
What's under the stainless sheath? Rubber!
@@GarageTimeAutoResto mmmm. I think its not rubber, some other impervious material. But the SS lines will never leak, and there is no crimped areas.....I had it done to my 85 3.2, it was leaking and I just happened to notice....otherwise, could have been a disaster. I was just lucky. My Porsche mechanic had a hose place do it, took the original and they copied it.
@@GarageTimeAutoResto Hi Tom, that is the problem with most lines including OEM Porsche, new and old, they are made from rubber and there is no rubber that holds up long term to modern fuel and the additives in them. I would highly recommend you get some PTFE lined braided hoses, ideally with a PVC or Hytrel cover so they don't abrade what they touch, and they will last the life of the car then, for not much more cost. Paul Mason makes a really nice kit that is sold through Pelican, but you can source and build them yourself quite a bit cheaper, so I'm sure that's what you will go with. Happy to chat about good sources, highest quality is probably Aeroquip Eaton, but Russel, Earl's etc all make them as well.
I like your dial indicator adapter. Is there anything to attach a similar one on a 356 head? Looks much more accurate than adjusting by feel.
Thanks,. I haven't thought about this for 356 because the access is so much easier. I'll think about it though.
Feeler guages can be a bit tricky..
Ever done the triangle of death or doom …. The oil leak on the top of the engine with engine in the car?? NEAD HELP have mechanical experience but just unsure
Never done it, but it looks hard to access even when the engine is out! Best wishes cheating death😂
Seems like a pretty healthy engine overall and a good basis for your hot-rod. Did you re-test cylinder #1 after adjusting the valve? I will need to look into that block for measuring the valve lash play - the makes a lot of sense. I actually bought Kirk's valve adjustment tool because I didn't want to fiddle around with feeler gauges. Thanks for the links to the products too!
I didn't re-test after adjusting the valves because there was clearance. If the clearance was negative, I would have tried again.
I'm glad you liked my valve checker tool. It's got a few problems that I want to improve.
@@GarageTimeAutoResto Understood. Looks like something you might be able to sell when you've perfected it?
I would NEVER turn the engine backwards...sorry.
Why? everytime you shut the engine off it goes backwards a little. The timing chains don't care either.
