Oil Consumption Thread

[az3579]

Did you do any blueprinting on the engine you are rebuilding? Just curious to know what you found.

I had to look up what that even meant, so perhaps that answers your question.
It sounds like too much work, honestly. I'm working on the engine in my friend's garage about an hour from me in the little free time I have, so I like to maximize my work time when I'm there.

I also have a m54b30 on the stand now and while I don’t have the numbers in front of me I did have excessive wear on the oil control rings. Luckily my cylinder bore measurements were still within normal tolerances. Haven’t decided what to do for new rings yet myself. Honestly, I’ll probably just go stock.

If I understand it correctly, the current ring design for the M54 is a revised design that's supposed to be better than what we had from the factory. However, I still didn't want to take the risk and the M52tu/M54 combo route appears to be pretty bulletproof. Of course the downside to this is having to buy two sets of piston rings.

No problem, man. I fully understand.

That’s interesting info. I’ll make note of that when I decide.

I'm in the process of rebuilding a spare engine for my ZHP since my rod bearings are toast. I will be using a combination of the M52tu and M54 rings on the new build, which should hopefully nearly eliminate non-standard oil consumption.

I'll let y'all know what happens over the course of the new few months.

Post photos and write up to the Forum Projects when you are done.
