I had the hose that feeds the turbo coolant blow out on me, so I replaced it with a 3/4" hose.

On my way to work this morning I noticed some smoke from under my hood, it was just the coolant hitting the engine from some leaking.

Anyway, What are the symptoms of an overheated / blown turbo?

I'm making about 5lbs right now, but I might have bumped the mbc wrong (it's pretty crappy), or I might have messed with a vacuum line (but I'm getting 20 vacuum at idle)


Thanks for your help guys!

How do I check for oil in the intake manifold? do I take that rubber fitting off that goes from the IC pipe to the intake? That's a little torn so I'm hoping not too, I havn't gotten a new one yet, and I currently have it so it's not leaking air -- I'll figure it out if I need to.

Can still hear the turbo spool (sweet noise, makes me smile every time)

Turbo is being pumped water into, however there was three times in the past two days it didn't happen (did city driving before this occured, so it had decent cooldown time)

I can pinch the vacuum line to the WG and post back (hoping this isnt' a different procedure)

If I get this right, there should be uncontrollable boost.... right?


Again 20 vacuum at idle... Does this mean it's not a vacuum leak?

PS - Did plugged mbc test -- Made plenty of boost.

Should I just turn the MBC WAY up and see if it boosts?
1 full turn didn't do anything...

Then again, I can never remember which way is up or down

I turned it like I was loosening a valve... but it's the - direction on the ****, so I dunno...

Anyone else buy the MBC from lindsey?



Does the MBC bypass the KLR?
Does the Lindsey Boost Enhancer bypass the CV?

Thanks!

Lorax

what boost controller do you have?

mortymower

i would say the lindsey one

"Anyone else buy the MBC from lindsey?"

Indeed, the lindsey one

Could this be the cycling valve? I thought I bypassed it, in fact I was sure I bypassed it! Am I just being stupid?

is the cycling valve totally disconnected?? The line going to the inlet to the turbo should be capped- i traced mine and put a bolt in it under the intake and clamped it. The one going to the wg and IC line should be connected- i used a T there and connected the lower part of my Dual port WG to there. Other side of the lindsey MBC goes to the top of the WG if you have dual port. If not- one goes to the T and other to the WG.

Cycling valve delete

It was running fine at 15lbs not three days ago, how easy is the cap to come off?

I think it may be my MBC. I'll check for the caps
