Are these #s ok?
I have a 96 d16y8. Stock everything.
We put together a turbo kit, installed it, tested the car on 5 lbs...idled fine & drove fine.
**1st test run** 1st problem- radiator cap blew...replaced it.
2nd problem (same night)- car started overheating. Coolant was boiling and overflowing out of the reservoir tank (head lifting?)
Fast forward... I had the head resurfaced, hot tanked, replaced all the seals, new oem headgasket, arp headstuds, new intake mani gasket, etc
Installed everything and tested the car OUT OF BOOST... seemed to run fine, no overheating issues.
Now today, a couple days later, we checked the compression... and here are the magic #s
150-170-160-150
FYI- the car has 180k+ miles.
Now... should these #s alarm me? Correct me if Im wrong, but the compression #s could vary by 10-15% of the highest # right?
Any advice would be helpful... keep in mind... the motor has 180k+ miles. Everything was working fine before the install.
TIA

Re: Are these #s ok? (Evil Empire)
doesnt sound too bad at all, the motor has 180k so you cant expect it to be mint. Id say as long as it doent smoke like mad and overheat you should be cool with those compression numbers

Re: Are these #s ok? (SOHC_MShue)
yea I was about to buy a y7 for 100-150 I think... But we looked at the car, im not gonna be too bothered with the compression for now... its not THAT bad. I am gonna run thicker oil though... ive been running 10w-30.
We got the idle a bit better... now it just needs to be tuned!
And then theres another SOHC Turbo ninja roaming the streets of Miami

DON'T RUN THICKER OIL
The oil galleys, passages, and holes in your engine do not change size over the life of the engine. If it was designed for 10W-30 when it was new, then it still should have 10W-30 in it now.

Re: Are these #s ok? (8200RPM)
I've also been told to use the recommended oil...Everything in the engine was designed to use that specific oil so you CAN use other oil but it could be detrimental to your cause....
IMO the best thing you could do is just up the quality of the oil you'd be using not the "thinkness" or weight...

Maybe, I don't know what the manual calls for. I used 10W-30 as an example because that's what he says he is using. If it's 5W-30 in the manual, then you should still be using 5W-30 at 200,000 miles.

Because there are VERY few people in the world who actually know what they are talking about when it comes to the oil they use.

Yes, I have seen MANY cars with engines wearing out long before they should have simply from running too thick of an oil. If the engine was designed for say 5W-20 oil like so many are today, then the passages and holes in the bearings are very small, and the tolerances are very tight. Thick oil does not run so well into tight areas, and you end up with more of a chance for metal/metal contact. Run the oil weight that the manufacturer recommends if you are on a stock motor. If you are on a built motor with different tolerances and different bearing sizes, then run what your machinist recommends, assuming your machinist is not an idiot...

Re: (SilverSellout)
No need for apologies... its not a big deal
Its just kinda like if someone referred to you as a chick, your macho ego would probably stand up and say "hey im a man!"
So anyway, thanks again for your help/opinion... I took it under consideration.

This would have probably been my first hint telling me to wait a little longer and turbo later.

Re: Are these #s ok? (INVALID)
This goes back to the oil posts earlier.
You were talking about how you shouldnt run thicker oil than what's recommended because the oil would be too thick to get into certain passages. What about running thinner oil? For instance, would it be okay to run 5w-30 in an engine made for 10w-30? From what I understand, the only difference is that the 5w-30 oil is thinner than the 10w-30 oil when they are cold. Once warmed up, they are both a 30 weight, correct?

Yes, once warm, they both flow like a conventional 30W oil would at warm temps. If you live in an area that is cold, then you should run a little thinner, like 5W-30 or even 0-W30 if it's really cold.
