just baught my car /w this "freshly " built motor like a month ago.. supposedly:

Engine:
B18B 1.8L Non-Vtec Head
- Port and Polished
B20 Block
- Bored/Sleeved 84mm
- Sleeved by Golden Eagle
JE Pistons 8.0:1 and Piston Rings
Eagle Rods
Turbonetics T3/T4 Hybrid Turbocharger
Rev Hard Turbo Manifold
tuned on chrome @ 6 psi.

got a noise from motor within 3 days after purchasing car from testing to see if rev lmiter would kick it (rev'd it to 7.5krpm) barely went anywhere with car, thought it was a rod knock.. did valve adjustment, noise still there, then 2-3 weeks later took it to BSERIES and finally deteremined that it wasnt a rod knock, and might be Piston slapping wall due to error on person who machined it, or whoever built it just pieced it together and didnt know how to measure it. did a leak down test, resuls were bad. 2 of them did not hold pressure, turned out to be valve seals most likely, another had bad piston ring due to oil on sparkplug. planning to just drive it and baby it, wondering if i got the correct oil to use.. was running 10w30 fully synthetic, but now baught Valvoline Racing 20w50. dont know if its too thick but thats what i remember someone tellin me , to get thicker oil and just baby it.. so wondering if i got the correct oil, and if so is it safe to use w/o ruining my turbo seals or anything..

valve seals wont cause low leakdown....

but use some cheap *** oil cause if its that bad its just gona burn it up

start over IMO...

eg crunkmonster

it was mineral oil used to break in motor..

J.nguyen

Ok, well i did the oil change anyways b/c nobody really was sayin much ... also searched on HT said it should be koo.. but after i did oil change i noticed taht my motor started to make a different noise now.. and it idled a lil bit differently. also after a 10 min drive, i see oil coming out of my turbo where the filter suppose to be.. hmm..

also when i did my oil change, saw my oil, my password jdm magnetic drain plug catched alot of wierd stuff on it.. looked like grey greease?? iono and my oil was wierd.. not normal...

JDogg

think about it man... valve stem seals go at the top fo the guide... they have zero effect on leak down.

its either toasted rings, bent/burnt valves or a headgasket is done... thats all that effect leakdown for the most part.

the grey grease is bits of aluminum.... that motor is done.

eg crunkmonster

last time i saw grey in oil, the motor had a spun bearing

probably bent valves.. but my idle isnt fcked up..

bits of aluminum.. from where?

yeah.. i guess its a done motor.. probably just drive it until it blows then swap in a stock motor.. (anything wrong with doing this? or can anything be salvaged from it?)

first oil change after motor rebuild the gray grease may be assembly lube???

they why would it stick to the magnet?

bent exh valves usually wont mess up the idle much.

ic.. so might have bent exh valves?

rtype11

yeah well your pretty much out of luck then, was hoping it was like arp cam lube, which is a grey grease collecting on drain plug.

very good question.. didnt think about it.. so what can this "grey grease" be?? when i touched it, didnt feel like it was metal flakes, but when i rubbed it onto a rag, it looked like grease...

nfn15037

Well if it was stuck to the magnet then it is obviously some sort of ferrous metal.

JDogg

excuse me... bits of bearing

bits of bearing?? so its gonna become a rod knock??

nfn15037

Bits of bearing means that you need to remove the motor and disassemble it. Regardless of what it will cause, the motor needs to either come out now or come out when it blows up. The block and crank may still be salvagable now, but probably won't be once it kicks a rod through the block.

If it has adjustable cam gears make sure they are tight. I had 1 bolt on my edelbrocks get loose and it was noisy. Tightened it and all good. check for little things like that, maybe the timing belt is rubbing on the plastic cover or loose pullies.

looks like u bought someone's bad build. its prolly not even a build block and just a SSAC kit...
