Hey everyone. Thanks again for helping me get this sorted. I built a leak tester out of a balloon and an old vape.
It looked like a large leak was coming from the bottom of the manifold where the gasket seals.
When I pulled off the intake this is what I found.
Must've been an installation...
Thank you DSMPT and bastarddsm. I'm pretty sure I'm uploading my log file with this. The major changes in Lambda were caused by me making major adjustments to the idle VE table during the log, I also changed the idle base position from 30 to 5 over the course of this log. I'm pretty sure my...
I haven't done a leak test, I don't believe I have the equipment to. I am thinking vac leak could be the culprit because the car used to idle nicely on pretty much the same setup (just 8.5:1 pistons), in pretty much the same weather, and the exact same ECU settings. However, upon first startup...
Yeah, a slight correction there (the gauge I was using tends to get a little stuck around 50psi) after a couple more startups, it unstuck and I was seeing 75psi on cold idle.
Hello everyone. I am trying to get my car to idle decently (2.0L, 9.0:1 pistons, eagles, FIC850 Injectors) I want to insert my most recent log file, but I don't know if I can here.
What I'm dealing with is very lean rough idle. I've turned off idle, and lambda feedback, and ign trims, and am...
I appreciate the help very much. I swapped my turbo and gauge feed locations so now my turbo is getting oil through the stock head feed, and my gauge is down on the OFH. I saw 40 psi cranking and over 50 at idle.
Thank you very much. I knew I took that apart for a reason. I'll make a T off my current turbo feed, which comes from the OFH and check pressure there.
Update, so I really have no idea how the oil pressure relief valve works, I'm trying to figure it out. But I think I did something brainless when putting things together, which is causing my problem. This is what my relief valve looks like when I pulled it.I'm assuming having things...
I know I'll probably get poached for this, but I need some help figuring out my situation.
I've got a fresh built 7 bolt 2.0l Supertech pistons and eagle rods. I'm positive all of my bearing clearances are great! (0.0028 on rods 0.0025 on mains)
I have low oil pressure at cold idle (haven't run...
Thanks for all the advice everyone! Just thought I'd share what I've found.
My head gasket looked like it's been there since the factory when I pulled it apart. It's only been on a few months and hasn't gone through a single heat cycle but it's falling apart. I could'nt identify exactly where...
Thanks for all the replies.in that case I'll probably leave the oil pump on for now. I'll cut open the oil filter though. I'm on a bit of a timeline with this car and would be best to make due with what I have on hand. I should have the head gasket done today assuming the head and block are...
Sounds like a good call.
By compromised you mean flakes of metal and debris? I doubt it could be out of spec after so little operation.
Is a fairly fresh oil pump gasket reusable? I don't think I have an extra.
