Not a BHG holy crap!

Okay so Because my car was puffing white smoke once in a while and Would smoke black sometimes I thought BHG for sure so I bit the bullet and took it in 4 Diag. Turns out I have oil leak in my Turbo return hose gasket and coolant leak in my Throttle body somewhere which is the white smoke. They also said my car was idling on 5 cylinders. I pulled the plugs and Cyl 5 is Black as hell. My mechanic friend told me it could be because it is untuned (SAFC is untuned) and I have the Lex/550 mod. I also hit abnormally low fuel cut. The engine does not shake AT ALL at idle. But something is obviously up with cyl 5, could it be an overfuel problem caused by untuned safc?

Did you even do a compression test?

 

[87Superdupra]

I will have done by the end of the week, don't have my own.

 

[JustAnotherVictim]

Definately have that done to confirm.

I 'by-passed' the coolant feeds into my throttle body about 4 months ago. I just pulled the hoses off it, and put them together with an 8mm (5/16") brass pipe and hose clamps.

I did it to have a 'cooler' throttlebody for cooler air intake. I like the performance much better now.

If your leak is in the ISC, you can by-pass the coolant , same as I did on the throttlebody, but you should probably get a new one.

sounds like you have a boost leak also. check over your intercooler pipes as well. this could explain the abnormally low fc.

Just wondering, how would one conclude that there is a leak in the throttle body or ISC valve? I assume you pressure test the coolant system?
