Renault 5 GT Turbo / cylinder pressure test, does this look right?
« on: 13:08, Sun 22 March 2009 »
looking at doing a full bottom end rebuild so tought ill test the pressure as i might just do the full engine, piston rings the lot. what do you think is it worth changing the rings ect ect.....

I tested cylinders 1 to 4 from flywheel,

cylinder 1
dry test = 150psi
wet test = 160psi

cylinder 2
dry test = 148psi
wet test = 162psi

cylinder 3
dry test = 170psi  :shock:
wet test = 176psi  :shock:

cylinder 4
dry test = 142psi
wet test = 150psi

i did cylinder 3 three times cause i thought the guage was reading wrong put its right.

What do you guys think, is it worth changing or just leave it alone :?:

where should i start.

Finaly got my car on the road so i decided to set the boost to about 11psi
then had a problem as it kept cutting out, so sorted that by unpluging the overboost sensor on the short turbo pipe.

Right all was ok, so when up and down the road a few times it was ok no problems, but then it started to loose power about 5k revs from turbo on boost, felt like it was jamming.
so pulled over and felt the shaft was very loose and touching the sides of the housing, so i just thought the turbo was on his last legs and i killed it.

SO i managed to get a second hand turbo with the shaft in good condition with minimal play what so ever! so fitted it to my car and before i connected the oil feed pipe i decided to start the car to see if oil was getting to the turbo and yes it was poring out and back into the oil return pipe.

So went up the road and was boosting really well up to the letter 'B' on the turbo gauge thats about 9-10psi was loving it :P  so kept driving it around just to make sure everything was fine, then my oil light came on :?(Note:oil pressure gauge on dash dont work)  so went back home checked oil level and it was at the max, so went back out started boosting it up the road then...........It started doing it again plus the oil light came on again, pulled over took the airfilter off and the shaft was slack as hell :shock:  what the hell is causing this only went up the road 6 times :?:  :?:  and now the other turbo is the same as the first one loosing boost about 5k revs and slack as fook. cant understand how the turbo got so slack in a short time as it was a solid turbo :?
Also is the turbo ment be be spinning when idleing?? car was idleing under 1k and the turbo was spinning is that normal :?

help needed as im running out of money :cry:
