I was getting a horrible vibration from the engine plus lots of blue/black oil smelling smoke from the o/s exhaust. I relocated and changed the PTU and replaced the original exhaust with a mongoose catback. I also replaced the throttle, IC and rad hoses for silicon ones and finally, flushed the coolant,changed oil and filter. The engine now no longer vibrates like it did (result!) however, I'm still getting smoke from the exhaust. Thing is, it's now coming out of the n/s and the o/s is clean :confused: All the guages are reading correctly and as expected, however my AFR gauge says that both banks are running lean.

I was thinking that a turbo seal was packing up, but now i'm not sure. While swopping the IC hoses, I did notice what looked and felt like little blobs of tar in the hose :shock:

Anybody have any ideas?

cheers

anyone?

could be a turbo on its way out or a weak PVC valve

would a pcv fault cause smoke to come out of just one exhaust? The turbos boost perfectly, would the boost drop if the seal was leaking?

Sorry i'm not a mechanic and the zed is the first car I've ever tried to repair/rebuild.

Quite often a zed tt with dead pcv valves will not smoke if left to idle for a few mins with aircon on, turn aircon off, tickover slows+ then it smokes?

Anything else, worry, or stop looking behind you :wack:

might be worth changing PCV valves cheap fix if it works.

Update: I started the car today with the AC on and NO smoke :hyper: So is this definitely duff PCV valves? Didn't want to spend too much on this engine as I have a low mileage rebuilt one out of my breaker that I was going to fit, after I'd done a bit of detailing on it.

 

So dilemma is do I replace the PCV valves and get a bit more out of this engine or do I put the known good engine in now and forget the detailing?
