I just built my new motor. B18 a1 with srp 8.5 :1 pistons, Eagle rods, acl bearings,gsr oil pump with a v tec head. I have 44 miles on block sofar and its smokin a bit. Im a lil worried , is this normal? somone help me out

 

Till the rings setup you will see some smoke.

 

WAS IT SMOKIN B4? if so it could be alot oil in the exhaust and its burning it off

it smokes at idle sometimes and under vaccum. Its makin me nervous as hell. Especially reading all these break in threads. i dont even wanna drive the thing now

 

Mine smoked some when I broke mine in, how many miles on the motor now?

 

44 miles

 

Me and my tech are gonna pull the plugs and see what we got. ill keep u guys posted.

 

what was your break in method? How are A/F's and timing. The rings should be seated enough by 100miles that no smoing should occur. I always use the hard-break in method BTW

 

after 44 miles. The plugs look just liek they should. No oil on them or anything. Im starting to belive that a seal may me blown in the turbo and causing the oil burning. Gonna take off the boost pipes and check.

 

i always ran my **** hard for the first 25-50 miles (not ***** 2 the wall hard) to seat the rings
the rings cant un seat their selves
we just rebuilt my boys **** and it smoked bad for the first 3 tanks of gas (~900 miles) and now its fine just keep check on your oil cause my boys oil always stayed full so we determined it was the **** in the exhaust

O and on mine i was runnin open down pipe since i rebuilt my motor and when i hooked up my exhaust she smoked like crazy then it stopped after i beat the **** outta it all night long (when i blew my motor oil was pouring outta the muffler so it was alot of **** in there)

should i be running an oil restrictor? im using 4-an line. maby putting 2 much pressure on my turbo?

 

Which turbo? I had my broke in on the dyno. It smokes only becasue of the 11.5-12.0 A/F ratio at WOT. That's becasue it's supposed to. It does not smoke at all otherwise. I have about 700 miles on the new motor. I have the SRP pistons too only 9.9 CR.

 

keep me updated

 

hmm..mine smoked for like 5mins, then no smoking..

That could have been due to the assembly lube burning off in the initial startup. Right?

 

Heres my snail t3 t4 60 trim

 

Those plugs are pretty rich. I should be able to see the whitness of the electrode. The base of the spark plug (called the ring) is where you look for signs of lean/rich mixtures NOT the electrode.

2.) RUN IT HARD. The rings seat by the pressures in the cylinder. The gas will force the rings against the walls and the declerations will hold the rings set to that position. It's easy just floor it too redline (now that you have some miles on it cause otherwise, I wouldn't redline immediately) and let the engine break all the way back to idle. Repeat this for the first 100 or so miles then do it often for about 500 then it's pretty much broken in when you compression check it.

fix your AF's though

 

could be oil from the turbo getting past the seals if you're not running a restrictor, what oil pressure readings are you seeing?

when I first started up my built motor w/ rebuilt turbo I was seeing 80 psi at idle (cold) and was getting a lot of smoke. put in a restrictor and no more smoke!

 

That makes me feel a lil bit better. I have a oil line restrictor being made at the machine shop as we speak. cant wait for an atp one. Im gonna try it and cross my fingers. Thanks for the help guys ill keep u posted.

 

Mine never smoked at all, That oil line is definelty too big so that restricter should help out alot, I would fix the A/f's and run it hard. I recently was talking to one of the guys who works at precision turbo (located in Hebron) and what they do for oil restricters is cut the tip off the fitting in the turbo, bore it out a lil and stick a nitrous jet in there. He said it works great and they do it on many of there cars. Has anyone else done this?

 

O yeah, those arent bosch platinum 2 plugs are they? If so get them the hell outta there.

 

NGK BCPR7ES are good plugs. Give them a try.

 

the motor isnt seeing boost pal so no worries. and there not bosh.

 

thats a good idea with the nitrous jet. But it has to fit a flared fitting correct?

I made my 1st restrictor out of a carburetor jet from my old motorcycle, worked great so I don't see why a n2o jet would be any different
