@@ignaciorodriguez5001 Absolutely! It’s no wonder that almost any engine related work is an engine out job on these models. Best to take care of everything at once while it’s still out.

@@bogdannegrut-ou5xx Thank you! I believe it has something to do with the weight of the connecting rod as these (the whole piston assembly) would ideally have to weigh as close to the others as possible.

@@azerdedic5290 If you have checked the timing and are 100% sure it is spot on, then there are only 3 possible causes for this: either the head gasket was not the correct one (could be a packaging issue), the machine shop that has been done is not in specifications or the valves are not the correct ones and ptotrude inside of the chamber too much. If you end up taking off the heads, while the head gasket is still on, the piston’s head should not protrude over it. If it does, then the issue is one of the 2 afore mentioned.

@@krzysztofmazurkiewicz9831 Thank you! It will most definitely be as detailed as I possibly can to provide more information on this platform!

Indeed, very demanding! But that’s what makes it even more satisfying in the end

@@BiTurboMechanics Vrlo je problematicna nabavka rezervnih delova mali je izbor aftermarket komponenti a to znaci da ce cene biti astronomske

@@bobansupergenije7512 Yes, this is exactly what I am going through right now trying to source a used engine :/

Let me know if you have any advice regarding that

@@anuvind-tp Glad I could help and good luck with your search! They are great cars once you deal with the maintenance. If you are interested in searching one for a rebuild, make sure that at least the parts you do not want to touch are as close to perfect as possible (like the body panels, the paint, no rust and so on) and take your time with it to find the right one for you!

@@BiTurboMechanics Thanks, definitely taking my time on this one 👍🏽

Could be, but given this car was completely stock, what I believe to have caused it is the debris found in the oil pickup tube combined with the wear the engine and the oil pump had. These led to the oil pressure dropping, a main bearing spinning and from there you’ve seen how it all went down.

@@BiTurboMechanics how many mileage has this car ?

@@krzysztofmazurkiewicz9831 Just over 180k kms, so roughly 112k miles

@@cwinner6277 Thanks a lot! It’s gonna be an interesting one to say the least!

Thanks! The torque for the camshaft carrier is 13 Nm, but you must also follow the tightening sequence I used in the video.

The tightening torque for the cylinder head is: 1. 70 Nm 2. Release 180 degrees 3. 50 Nm 4. 120 degrees 5. 120 degrees It is ok for the connecting rod to have some side to side play (albeit as little as possible), but it is best to check your clearances using plastigauge to make sure it is well within specifications. It depends very much if you are referring to only spinning the crankshaft with no connecting rods installed or with them installed. If your clearances are on the tight side, it might be tougher to spin than after running it in, but the amount of force required to rotate the crankshaft alone should be as even throughout the whole range as possible.

​​@@BiTurboMechanics First of all, thank you very much for the answer My entire crankshaft has a bit of play when I try to move it right and left, maybe it's the axial bearing? The engine had a timing chain break, so I have a new camshaft, new valves, new chain. I started the engine and it rattled. I've now got everything out again and in parts, the bearings look very good, but as you said I'll measure them all again The crankshaft is very easy to turn without the pistons, but with the pistons it gets really difficult to turn at times I would be super grateful for your answer, you help me a lot.

⁠​⁠​⁠It is normal for the crankshaft to have axial play, that is why the axial bearing is in place. On these engines it is located on the middle main bearing, but as I’ve said, a little play is perfectly normal. The rattle and the hard to turn spots could indicate some issues with the pistons themselves, so make sure to also inspect the cylinder bores and the pistons themselves to make sure no debris found it’s way into them and is slowly but surely ruining the block. Other than that, if there are no obvious signs of wear on any of the parts, the issue could lie within the auxiliary engine parts.

​​@@BiTurboMechanicsI have another question for you, I installed a used but good camshaft, the thickest cylinder head gasket, new valves and 2 new rocker arms then installed the engine and the valve clicks.. timing chain is adjusted 100% correctly Bearing shells are still good and apparently the crankshaft is too What could be the error that causes the valve to still come on?

Thanks a lot!

Appreciate it! Hope you'll also like the latest one on the channel as well!

@@gezata Hahah, I rarely use them for tight spaces or to speed things up, but preffer it the old fashioned way. Thanks, it’s on the way!

Thanks for the comment! Had you watched the complete video, you would have seen that both the piston and the grooves where the rings sit have been thoroughly cleaned. There is no need to replace the rings on an engine I am not doing a complete makeover on, and even so, the car is running perfectly to this day.

Woah, appreciate it a lot! Loved your N/S63 videos.

Thanks a lot, hopefully we’ll also reach the same quality of work! I am based in Romania

@@Andreixl05 Thanks a lot!

@@LiviuM-p8e Hi Liviu, no, that was the noise coming from the spun bearing, the timing chain only makes a slight metallic noise on the first startup.

Haha, thanks! She’s happy to get her hands dirty whenever it’s required

@@arctican7483 Thank you! I am currently cooking it!

Thank youu! Currently wrenching on it!

@@kat0197 It always comes down to how bad the crankshaft has been damaged and the availability of second hand parts. In this instance, I could find a good second hand crankshaft rather easily. Either way, both should work considering you find a good machine shop.

Good question which I actually forgot to answer in the video! I believe the issue was caused by all the debris I found in the oil pickup tube. It was clogged with bits of rtv and a lot of hairs so it is pretty self explanatory how the oil pressure got too low for the bearings not to spin. To make sure everything is fine after the install, I used the oil pressure gauge while the engine was at operating temperature and it was reading well over 1 bar of pressure (approx. 1.4 bar) at idle which is well within specifications.

Multumim!🤍
