Well progress, the hesitation issue has now gone. car running smoothly again, then today got her up to temp went to move her, and low and behold a bloody swimming pool forming under the car. turned the engine off and checked.

 

Water leak is back, but noticed it does it when the engine is warm, when its stone cold, it doesn't, so going to empty the system out over the weekend and check the top rubber pipe work. also going to get the rad out, take the plenum off, clean everything check the water pump, flush the radiator through, and if needed change the water pump, top inlet pipes, clean all the radiator rubber hoses, water by pass, and polished plenum on. may as well as shes going to be off the road for a few days chasing this water leak. ill update this thread with photos, now I've found my camera, and get a walk through up as well while I'm at it.

Doh!

Wot a complete pisser (no pun intended!)

 

:oops:

how did you sort the hesitation dude?

detailed pictures at the rear of the engine would be nice bud when the plenum is off? :thumbup1: thats where mine is leaking and im going to try and do it over the weekend, (if i get a minute or two!!) i had a good idea where my leak was coming from due to steam, do you not get a bit of steam?

thanks bud!

Yeh , do plenty of pis if you can vods, I`m doing the plenum off jobbie soon

I refer to my previous post :stupid:

wow i go sleep, and look at the interest I've stirred, don't worry ill be getting loads of car porn pictures, and yes Jeff, you were right, doing a flush made it worse but at least its nice and healthy water / coolent.

 

As for the hesitation issue, i ran down to the car the other night to try changing over the PTU, changed it over, tried starting the car, but she wouldn't fire up on the new PTU, so put the old one back on after cleaning the connections. must of caught it when doing the power steering pipe, as she hasn't been hesitant since.
