Ryan_EP82 GT Posted November 6, 2013 Author Share Posted November 6, 2013 Thats true, hopefully it is something minor. On another note.... is that you're R35? lol Quote Link to post Share on other sites
TurboTobz Posted November 6, 2013 Share Posted November 6, 2013 I wish buddy, my car is turbo… Diesel french megane crap, just looking for a starlet again (Number 3) THINK I have found one worthy of viewing this weekend but that is literally it everything else I've seen looks like it's been dragged through halfords backwards or raced around macdonalds endless amounts!

Chris_GlanzaV98 Posted November 6, 2013 Share Posted November 6, 2013 i would do a compression test and if all is well your and your not loosin water, then its most likely condensation in the exhaust it will take a short while to clear, give it a good run and some boost through it should clear it Quote Link to post Share on other sites

What you thinking of bud gt or glanza?i would do a compression test and if all is well your and your not loosin water, then its most likely condensation in the exhaust it will take a short while to clear, give it a good run and some boost through it should clear it Thats dead on im gonna get that done tomorrow then. Looks as though all vac/hose lines were the right way aswell, so im hoping it was just condensation.. It was sheet white every morning from sunday to this morning so probably would be a brave bit of moisture! I'll take it for a short run when i can and check the water levels, whats my position if its using lots of water? Could it be head gasket related even after a rebuild?

russ78 Posted November 6, 2013 Share Posted November 6, 2013 depends if all head bolts were all torqued down correctly bud, could well be hg compression test will tell u everything u need to know Quote Link to post Share on other sites
Ryan_EP82 GT Posted November 6, 2013 Author Share Posted November 6, 2013 (edited) depends if all head bolts were all torqued down correctly bud, could well be hg compression test will tell u everything u need to know true. thanks mate. do i do the test under wide open throttle as in foot down? my friend said not to bother with that just crank it for 7-8 seconds, any reason why you do it either way?

russ78 Posted November 6, 2013 Share Posted November 6, 2013 not sure if that makes a difference but ive always done compression test at optimum running temperature or not cold lol that will most definatly make a difference..... Quote Link to post Share on other sites
Ryan_EP82 GT Posted November 7, 2013 Author Share Posted November 7, 2013 No worries thanks mate, would there be a difference in the readings hot or cold? Quote Link to post Share on other sites

Ryan_EP82 GT Posted November 9, 2013 Author Share Posted November 9, 2013 I did a compression test there using a good snap-on tester and found: 85, 85, 84, 85. Now I don't know an awful lot but I know somethings up here? Engines only rebuilt, not by me by an engine reconditioning company and has only had 20miles run in before the test...Now the engine was cold I must admit but I don't wanna start the engine up and let it run to optimum tempeature if there is something severely wrong here..feels like it!Anyone shed any light?

TurboTobz Posted November 9, 2013 Share Posted November 9, 2013 That's real low, did you try a wet test Quote Link to post Share on other sites
Ryan_EP82 GT Posted November 9, 2013 Author Share Posted November 9, 2013 Ino mate, bit worried here!What is a wet test mate? Is it for checking the rings? Quote Link to post Share on other sites
TurboTobz Posted November 9, 2013 Share Posted November 9, 2013 Drop a squirt of oil into each cylinder, it temporarily seals itthen compression test it Quote Link to post Share on other sites
Ryan_EP82 GT Posted November 9, 2013 Author Share Posted November 9, 2013 Right I'm going to do that now mate.What should I be expecting roughly?To be honest I was expectin about 160-170 there Quote Link to post Share on other sites
TurboTobz Posted November 9, 2013 Share Posted November 9, 2013 150 area give or take if it gets better there's ring issues if not poss head gasket Quote Link to post Share on other sites
daniel_g Posted November 9, 2013 Share Posted November 9, 2013 Was it overbored when getting rebuilt ?Idealy you want to do a 'leak down test' for this you would need a compressed air supply. Basically lets you know how much and where gas is escaping from in the engine, ie past the bores or through the valves if theyre not sealing correctly. Theres a bit more to it than that but you get the idea.The engine builders should have donw this before handing you your engine back. Quote Link to post Share on other sites
Whitenoize Posted November 9, 2013 Share Posted November 9, 2013 Heres a pic of the VAC/water lines.I doubt yours are wrong though because you'd have most likely used all your water on a 20 mile run.I reckon its down to the very low temps we're getting atm.Keep an eye on it though Ryan. Daniel you need to start charging people for this picture lol Quote Link to post Share on other sites
daniel_g Posted November 9, 2013 Share Posted November 9, 2013 Haha, i've put it up a good few times now, should pop up if someone searches for it. That pic was the hoses on my old silver GT Had just fitted a nice freshly painted inlet to it. I made up an ABS delete kit the next day, if you look on the firewall the brake pipes are open.

Ryan_EP82 GT Posted November 9, 2013 Author Share Posted November 9, 2013 I get where you're coming from Daniel makes a bit more sense to me that way! Thanks, and tbh I wouldve expected the leakdown test done, but I know for a fact they company closed early the day I got the engine back so it coulda been thrown together and out the door if you get me. And they hadn't noticed I'd left pistons with the engine so they didn't start the work til the day before I got the engine back - a bit off topic but there's doubts in my head thinking about it now.There was water lost in the 20 mile driving home so a headgasket is still possible. BUT.. I tried to warm the car up to do another comp and wet test, basically car got to three quarters temp and idle dropped real low so It was turned off and tested, thsee are the results:Half warm comp test - 89,98,92,86Wet test @ same temp - 99,99,93,85What am I looking at now then? Piston ring problem? Quote Link to post Share on other sites
Ryan_EP82 GT Posted November 10, 2013 Author Share Posted November 10, 2013 I got speaking to another fella who has built his own vauxhall racing engines and says low pressure is to be expected straight after a rebuild. Over the course of the bedding in miles things need to wear in i.e the valves become seated and as you bed the rings in as well as other things gradually the compression increases.

RobSR Posted November 10, 2013 Share Posted November 10, 2013 Potentially rings or did you re-shim the head? Quote Link to post Share on other sites
russ78 Posted November 10, 2013 Share Posted November 10, 2013 Personally I would say either the rings have been clocked incorrectly or you have headgasket failure due the fact you have such low results over all four cylinders Quote Link to post Share on other sites
daniel_g Posted November 10, 2013 Share Posted November 10, 2013 Thinking HG myself.Was the block skimmed too ? Might have been warped slightly. Quote Link to post Share on other sites
