High Compression in 1 cylinder others fine also smoke issue
- Thread starter dominicanpanda
- Start date
Ok guys well I rehchecked the cylinder after a clean and I got the compression down to 150 Yayyy I also found out that I already have a Lexus afm my question now is why does the oil smell like gas and is thin (cause of gas) basically it was running rich like I stated before the car use to stall after boost cause I thought bov need to be recirculated , but after I fixxed iscv that stall issue siezed ....could it be that the car was running rich because bov causing oil to mix with gas and becoming thin to the point it goes through turbo seals and causing it to smoke? Imma change the oil and recirc today I hope and see if the smoking will stop and I'm hoping to get wideband and safc to really see what the hell is going on with the car fueling
I also had car running palm over oil cap hole and felt no pressure and saw no smoke puffing while it was running only smoke was the idle smoke out the exhausst and the gray blue tint smoke after revving high

Lexus afm and stock injectors=lean as fuck. Stop driving it.
And the BOV not being recirc'd isn't going to cause the gas to mix with oil.
You really need to figure out what your dealing with. I doubt your running a Lexus AFM without 550 cc injectors. It would run like crap.
It sounds like you have a BPU 7MGTE already but sounding like a "home build". In that case, you really have to figure out what parts you have on the engine so you can actually fix it.
Wondering if you still have the charcoal canister by the ABS... right against the passenger side firewall. If that's deleted or not connected properly, that can cause a fuel smell.
Can you find out from the previous owner what upgrades are on it? I would guess that it has 550 injectors (difficult to tell without pulling the fuel rail), you have a 3" exhaust and upgraded intercooler (so may have an upgraded CT26) and you are running the Lexus AFM. No AFPR? Fuel pump upgrade?
You might have an excellent power plant, but not assembled quite properly (vacuum leaks, small electrical issues) or you could have a bunch of "slap on" used parts without much thought given to how they are on the engine.
Makes it a lot easier to give you suggestions/advice if you can throw pictures up and describe the engine bay in point form. We can throw you so many guesses and really screw you up... or you can start mapping this out properly.
Its pretty easy to do photos.. you have an album here you can add them to and then just copy the links into a post...
why did that one cylinder have 200 psi? Error in how you tested?
BOV not recirculated = improperly metered air going into the intake. The air it releases is assumed to be entering the intake already.

Ok so basically the guy who had the car doesn't know completely nothing about cars what so ever he got the car from someone else that done all this work but he doesn't have the modlist or anything ,he also told me that cause of the surging idle he replaced the tps, (which is now not calibrated) changed the oil ,and replaced fuel injectors , I researched my afm today and found out it was Lexus afm upgrade which now leads me to believe he replaced the 550cc with stock 440cc cause he also doesn't know what injectors he put in,....Imma have to pull the rail and look at the numbers and he still has old injectors he pulled off ill run those numbers when I get those from him, the turbo doesn't have Toyota on the compressor housing makes me think its either upgraded or knockoff replacement ,the car does run ok a lil misfire nothing crazy though.....as for the one cylinder high I checked it 3timws that day but yesterday I sprayed it down with throttle cleaner cranked it with no plug in a few times and re tested and it was at 150ish....I guess I'm going to have to pull apart everything turbo fuel rail etc. And see what I'm working with...
Well the turbo don't say anything the injectors got some numbers just can see it too well I shall take pics either today or tomorrow and deff post them Imma take apart most turbo today I hope I'm sort of busy guy
Assuming the oil consumption is high, and this is defined as qts/mile oil consumed (not colors of smoke and other vague attributes), then there are a number of potential culprits as outlined in the TSRM here. You cannot just jump to the turbo or the rings or whatever, you need to first diagnose it! Note that besides those it could be valve seals for example.
