Jodadej's Engine Build Thread

Naw its a standard Journal Bearing. I thought that they said they pulled the drain line to make sure there weren't any drainage issues but I'll double check that today to see if thats the issue. If there were drainage issues there would only be oil residue coming out of the turbo right and none on the up pipe? If it were oil rings or something in the heads that would be on both sides?

EDIT:

Jeremy, when you had so many issues when your turbo seals went, what happened? Can you describe when it would smoke, how you were driving when it smoked etc...

UPDATE 7-14:
I'm picking the car up tomorrow. Bad news is that in decel there is some blur smoke coming from the exhaust. The shop only did a 93 tune for right now. We're thinking that I need to drive it and try to put some break in miles on it before we crank up the boost or before the engine needs to get checked out. Drain line on turbo is clear, checking intake side tonight, exhaust side I'd clear. I'm hoping it's stuff still burning off.

Good news on 5lb spring it made 10 lb. With 14* for break in tune on 93 with only a pull to 5k it made 500/530.

Jason,

I had smoking issues as well. They went away when I put an "S" bend in the oil drain line. See the attached top notch artwork.

When would yours smoke? Adam said it was smoking say after a not so hard roll through the gears and then let off then boom.....smoke

or

After a hard pull and let off it would smoke.

Letting the car idle would seem to let the oil pool up and back up in to the turbo. The smoke would come when I would start off driving and would mostly burn off. I called precision about it. The tech was a douche and didnt seem like he wanted to talk to me. He said that there weren't "seals" in the turbo.

My issues were the same. While cruising and acceleration no smoke. It was after decel and coming to a stop that it would smoke. If it smokes all the time and during accel that usually points to the motor. Your case sounds like turbo imho. I did everything restrictor, larger drain fully vented crankcase etc. No help all three precision journal bearing turbos I had leaked.

Wasn't part of Jeremy's issue was the upgraded oil pump that was pushing too much oil?

Yea so if the oil rings were messed up or the valve guides were messed up i'd be seeing smoke constantly? Seems like an accurate statement.

If its only after boost or acceleration it would be crank case pressure or turbo seals?

Greg I'm running the 5.8 Gt500 pump with billet backing plate, TSS gears, and Stock 3v pump spring.

 

[Greg Hazlett]

I know everyone upgrades the oil pump to the TSS or GT500 but on Jeremy's oil gauge it was showing the pushing of a lot of oil which was probably pushing too much oil into the turbo which was why he used a restrictor to reduce the oil flow.

Jason, it's a combination of high oil pressure and crankcase pressure. There is always some crankcase pressure but under boost there is a lot more. The oil has to drain against this crankcase pressure with only gravity to help. I finally got mine to stop smoking with a combination of restrictors and breathers/PCV setup. Do you have a restrictor in the oil feed line now? You can run a .065 restrictor with your JB and still have plenty of oil flow. Comp has me running .018 restrictors in the oil fed turbos I now have but they are BB style.

This is the same as mine does.

 

[jodadejss06gt]

The driver side has the K&N filter on it while the pass side is vented through a catch can with no filter on the output side to prevent the dripping on my covers. Thats how it was before the new engine unless something has changed. Wondering if there is a lot more crankcase pressure with the new engine.

I asked them if they checked the oil drain for return issues...response was car was running and they pulled off the return line to make sure the oil wasn't backed up the line. It had a nice steady stream, with no restriction.

I'll get it back this afternoon and put some miles on it and see how it goes.

 

[JeremyH]

3v pump has high pressure as well. My pump is a frpp pump that still has 3v stamped on it. I will note when I went back to 5w20 from 10w40 with the oil less turbo setup that my oil pressure dropped from 100psi at cold start to 80psi. Warm idle pressure dropped from 50psi to 40psi as well. So even though they reccommend higher weights for turbo applications the increase in pressure may hurt.

 

[jodadejss06gt]

Maybe that is why I never had any issues with mine. I ONLY ever ran 5w20 Mobil 1 with 0 issues. They are putting conventional 5w30 in for more break in period. If everything goes well i'll switch back to the 5w20 after this change.

 

[retfr8flyr]

I would check with your engine builder as to what weight oil to run. If he set the clearances loose you will need better than 20W oil under boost. I run Amsoil 10W30 Signature Series in mine.

I leaked on the thinner stock oil as well, just a thought when looking back. Maybe thinner oil with less pressure is ok or the same concept of thicker oil at higher pressure.

So where are the vids lol

 

[jodadejss06gt]

So, I picked the car up last night. Drove it about 50 miles home and then 45 into work this am. I'm trying to get these break in miles quick.

As far as smoking, light accel(not quite to boost ~ 5-2 inHg) then let out it will smoke a little. Getting into boost then letting out there is more.

I found out that I had an -8an return before on my old setup and they put a -10 on now, except the bung that I had welded in my pan from the origional setup was a -8. Thats why the picture shows the -8 to -10 adapter.

Here is a quick video with my potato, for some reason it was on 360 when I recorded...though my default was set on 1080....either way....here it is... oh and rev limiter is at 5k for the breakin and it comes up quick.

great Scotts!

Update 8/13:
The engine is in the back of my Jeep going back to the engine builder.

Got the car back on 7/15 or so. Drove it about 200 miles that week. Saturday 7/19 I pulled it out of the garage smoking pretty decently at idle so I put it away. Sunday the 20th I pulled all the plugs to find this......

#7 was dripping oil when I pulled it. This was after it had sat a full day with no start.

My initial thoughts are that something in the head was leaking a good amount. I'm thinking intake valve seal or along those lines.

Car went back to the shop on a flatbead July 31st and I picked up the long block yesterday to take back to the engine builder. He assured me he'd find whatever was messed up as well as inspect everything else to make sure I got a good running engine back.

It really sucks and I want it back.....but I want it to run like it should.
