Hi guys, I really need yoour opinions on this one...So its a fresh built block and a semi built head (unknown condition on the head was told it had 500 miles). Car starts and runs just fine, just one thing I dont get I'm running on adjustable cam gears and when we do line up for timing I used the single line, so when we're checking timing shouldnt it be on the red line (middle line of the 3 lines). Mine always stays at the single line wouldnt that mean its BDC?

Lets get to the point, the car was driven for about 20 miles. I kinda pulled it to 5.7 ~ 6k ish and after that white/blue smoke was coming out from the muffler BADLY... I drove it home assuming its piston ring, and I got 8 compression all across... Took the header off there was oil coming out from the 3cyl..., and yea the car shot out a lotta oil through the muffler. Friends listed a couple posibilities they said it could be..:
-Spung bearings
-Bad valve seals
-Blown head gasket
-Blown piston ring
What do you guys think? My head is already off and I dontk now how to check the valves to see if thats the problem. I really need to get this fixed to get to work and school If anyone experienced this problem before please let me know what's the first step I should do

 

anyone?

 

it maybe a blown piston ring.

 

compression test was all the same for all four could it be ring?

 

Tuned yet?

 

hard to say, I'm dealing with similar issues in my ls vtec though, check out my thread for some ideas.

Leak down test will help.

 

Have you looked at the rings.

 

what i want to know is how was it running on 8 psi on all cylinders

 

ya no ****..... somthing is ****ed up here, sorry I can't help bud...

 

maybe you know nothing about motors but there is no way he would have been able to drive the car if all the cylinders had 8psi , so the op must have checked wrong

 

Im agreeing that it wont run on 8 psi, what your problem f a g? I probably know a shitload more then you do.

 

only thing u can do is leak down test to tell u what can be the cause

anything under 10% leak is still within spec
Air leakage Table:
Leaking out the exhaust = Exhaust Valve
Leaking into the intake/throttle plate = Intake Valve
Air bubbles in the top of the radiator(take off the rad cap) or into the adjacent cylinder = headgasket
Oil cap, Dipstick, Bottem end = Piston Rings

 

sure you do

 

I put gas on the 4 pistons and nothing leaked so I guess rings are still good, took off the oil pan to inspect bottom too, everything looks fine no shaving no nothing.

The shop inspected the head and he told me the head valve guides were installed incorrectly, something about them puttin exhaust to intake and intake to exhaust everything was mismatch. So he told me I needed a valve job. Hopefully this is the solution.

 

if thats what the shop told you they lied your gonna get hosed

 

what do you think it is if it's not the head?

 

it could be the head but valve guides are not specific foe exhaust or intake side the valve steam seals are , if the shop told you valve guides were specific they trying to screw u

 

Yea he did mention valve stem seals, I didnt really hear him clearly, he's done a couple of motor of mine already I trust him, I'm just hoping it solves the probem

 

From some of the readings that I have got from here on H-T. If oil is present on the exhaust it usually is the exhaust seals that went bad on you.

What is the condition on the bottom end?

Hopefully the valves didn't get bent prior to you owning it. Did the head come complete with the adj gears?

 

i checked to see if the piston ring were leaking, and it doesnt look like they were. Also dropped oil pann off ... everything looked good.

 

Are you referring to camshaft to crankshaft timing? Or setting the base ignition timing?

As much smoke as your describing Id rule out valvestem seals. You already took the head off, so you cant re-do your compression test. Theres really no good way to diagnose the problem now.An engine wont run on 8psi. Hopefully its not the rings or you just wasted alot of time and money...I think you should slooooow down before you spend anymore money unnecessarily...
How did you break in the engine? Run it pretty hard or kinda baby it?

 

just a fyi valve guides are different from exhaust to intake, exhaust guides are longer and Intakes are shorter.

 

I'm refering to the crank pulley there's a single line and a 3 lines, when setting timing you should line up the single line to the timing belt cover mark. But when the car is on, timing should be in the middle of the 3 lines isnt it? Thats what I'm refering to.

I brokke in the motor by running it hard for the first 20 miles. by hard I mean going up to 4 5k rpm and letting it slowdown itself not as in pullin the living hell out of it, and no it wasnt the ring we tested it, and all 4 cyls were good. The head is torqued back down already, I'm gonna finish puttin oil , coolant, and the rest in by tonight. Will post up result, thanks for all the feedback guys.

 

the single white line thats all by itself is the crankshaft TDC. This is what you reference the camshafts too.
The other 3 lines together are the ignition timing marks. I think its red. Base tming should be around 16 degrees BTDC.
Good luck!
