I am assuming that i just plug up the intake port on the single turbo, and hook up an air pump to one of the nipples and just pump until I reach a desired presure level and see if it leaks? But even if I do that, the air will escape via the exhaust. So I am not sure how I am supposed to do it..

If anyone has any instructions, please throw them my way. I figure there are not many lines to check... so it should be a lot easier.

Thanks

Cap the intake side of the turbo and run a pressure source to the upper manifold or better if you have a nipple on one of the intercooler pipes. Start pressurizing the system and listen for any leaks.

the way i did it on my talon when i owned it, was i took the intake off, and put a special coupler on the turbo inlet with a special fitting to accept and air hose, then i would pressurize the system to my desire..usually how much boost i was running and i would spray some soapy water around my couplers and anything else that holds air.

yeah i have a nipple on the intercooler piping for boost control =)

Sounds good.

Thanks a lot guys.

I've got a process that works great but your cheeks will hurt like a **** afterwards.

Do you think you have a boost leak or something dhahlen or are you just being thorough? I hope that everything is going good for you down there.

A little bit of both... I am going to take the car to Mazda.... if my engine is blown, I'm probably going to part her out. I don't have the funds to rebuild another engine (that would mean my 4th engine in 2 1/2 years) - that is just ridiculous.

I blew the first one due to old age, the 2nd due to stupidity, the 3rd from lack of a tune (but I haven't been boosting it cause boost doesn't work).

Anyway, I need to find the boost leak, and I also need to make sure it isn't blown. Lets just hope for the best.

i gots a compression tester... hopefully its not blown, didn't you just get that sucker in there??

how many miles on the engine? why do u think its blown

Where did you get the fitting and the white cap? How are they attached?

Thanks

PVC pipe and end cap and PVC cement. Drill a hole in the end and thread in an air compressor fitting. A cheap Home Depot Fernco coupler then connects the PVC to the turbo intake. Those couplers are cheap but will hold the pressure for short periods.

My turbo inlet is 4" so its harder to find a cheapass coupler that'll do that. I just need to cap the intake, I have a nipple on the intercooler pipe though.

2A+Ron - Yeah just got it in there.

Johnrxt2 - 17k on engine, crappy *** idle. Won't idle at 900-1000RPM, sounds like it's pinging. Read this thread:
