WOW abrupt engine issues on new jasper.

[Kuban]

Yea so i installed a new jasper longblock about 3600~ or so miles ago. Yesterday i did one full low boost pull (12psi) and i started smoking like crazy. Keep in mind i rebuilt my turbo like 3 days ago. I pulled over and checked it out. No oil leaks anywhere, but when i pulled the oil filler cap off, i had a little bit of combustion gas comming out of the pcv block tube. Not good. That right there is a for sure sign of blow by. How the hell does a brand new jasper engine help put together by a master toyo tech, completely properly broken in , have blow by? Im curious, cause this would be the second jasper engine i have had rings go on me within the last 4 months. Kinda pissin me off now. I dont think the turbo is what smoking due to the simple fact that theres blow by. If there was no blow by, then i would say its the turbo all day long.

I need input and recomdations please.

With the new jasper engine i was given a compete engine gasket set that we used to the fullest, new oil pump, and a procedure to flush out the oil cooler. So that system was checked, a checked,nd checked again.

p.s. after it started smoking the engine had a new tone to it. Sounds like a miss, also had obvious loss of power. I think i may have fouled a plug. But that doesnt cause blow by that im aware of

It's these cars man. It doesn't matter what you do to them they are just jinxed into the worst case scenario slot. This is the only logic I can lay on it.

I looked deeper into it (LOVE DOING THAT ON SUNDAYS!!!! NOT!~@#$%^&), seems as though my pcv tube was kinked a bit kinda cutting off flow to the intake and ruining the vacume. I took it for a test drive and its not smoking anymore. But that doesnt change the fact that there are combustion gasses blowing by. It still sounds like it has a miss. But it does have standard plugs in it. So im going to put these iridium 9's i got chillin here in and change the oil. Might even do a comp test while the plugs are out. Ill keep ya all updated.

Well i was talking to my toyo tech, he mentioned if the pcv airway was blocked for a long time, the excesive crankcase pressure could possibly crack a ring under a hard enough load. This coule be my issue. Anyone else think thats possible?

[suprra_girl]

if it was blocked then boost would be entering the block depths, it was only one run tho, and small blow by is normal

do a compression check and let us know the numbers

Ran a comp test last night when i changed out the plugs. Numbers went as follow from 1-6

175
175
175
175
110
175

As you can see 175 for dry compression test is right where i want to be although cylender #5 is dead. Im guessing ring damage. Thing is, If the backpressure was so hard i would have blown seals on the engine long before i would have cause this kind of damage, but it happened noticeably right after the race. On the last engine when all the rings were gone, i litterally poped the front main seal off the last time i ran it. Dont get me wrong i dont beat my cars by any means. I baby them unless im racing someone and thats about once a week tops.

Looks like its time to call jasper and see if im warrentee.
