Nick85 Posted February 2, 2014 Share Posted February 2, 2014 (edited) I've been suspecting that the rings may have worn as the car has felt underpowered lately and my catch can is filling pretty quickly, about once a month, (250miles). So I done a compression test across a all 4 cylinders and got these results. Engine details:- Been out for a 20minute drive. 110,000 miles running around 200-210bhp at 1.1bar or 0.7bar. Currently set at 0.7bar. Each plug when removed had some oil on them too. Indicating ring failure across all 4 cylinders. 1. 30psi 60psi with wet test2. 30psi 60psi3. 30psi 60psi4. 30psi 60psiCan they really be that low or did I do something wrong? Could the gauge be faulty?I've currently been saving to get the engine forged (stage 2) anyway but was going to have it done once summer is over. Can I still drive it as is now until the end of summer or is it a case of take it off the road if the figures are correct? Edited February 2, 2014 by Nick85 Quote Link to post Share on other sites
Turk Posted February 3, 2014 Share Posted February 3, 2014 They seem to be really know. How does the engine start up? If your oil catch can is filling up its signs of rings. But i aint no expert someone here with more knowledge should be able to help Quote Link to post Share on other sites

I personally thought it would idle horribly and throw out quite a lot of smoke too!! Quote Link to post Share on other sites
Chris_GlanzaV98 Posted February 3, 2014 Share Posted February 3, 2014 Im going to go out on a limb and say rings due to your story and the compression test results Your normally looking for around 150-170 psi iirc been a while since i done one but even so that is very lowAre you getting smoke fromThe exhaust ? And if so what colour ? Quote Link to post Share on other sites
Rosso321 Posted February 3, 2014 Share Posted February 3, 2014 Was that on open or closed throttle? Quote Link to post Share on other sites
Nick85 Posted February 3, 2014 Author Share Posted February 3, 2014 Just the usual amount of white smoke from a cold engine that clears up a bit once warmed up. I would have thought it would be throwing out a darker smoke In a higher volume! That was with throttle fully open. Thank for the info guys. Any more suggestion?

MARC MOSS Posted February 3, 2014 Share Posted February 3, 2014 seems odd that you had 30 across all four, I would try a different tester before anything else bud.. Quote Link to post Share on other sites
H_D Posted February 3, 2014 Share Posted February 3, 2014 try another compression gauge Quote Link to post Share on other sites
Chris_GlanzaV98 Posted February 3, 2014 Share Posted February 3, 2014 Actually this is a very good point, they do seem even so if it is the tester it could be a brighter outlook Quote Link to post Share on other sites
Nick85 Posted February 3, 2014 Author Share Posted February 3, 2014 seems odd that you had 30 across all four, I would try a different tester before anything else bud..This is was what I was thinking as the figures were so low. I'm going to see if I can borrow Gainzy's car and run the tester on his. If it shows similar readings I'll see if I can borrow another from someone else.It's going forged anyway at some point just trying to determine if it's got to be done sooner rather than later.

MARC MOSS Posted February 3, 2014 Share Posted February 3, 2014 I bet its the tester Quote Link to post Share on other sites
Gainzy Posted February 3, 2014 Share Posted February 3, 2014 I bet its the testerThat's what I said his car is running pretty good even smooth...will test mine tomorrow and let you's know Quote Link to post Share on other sites
Nick85 Posted February 4, 2014 Author Share Posted February 4, 2014 I bet its the testerBang on mate. Tested Gainzy's today and it confirmed a duff tester. Will get my hands on another tester that hopefully works Quote Link to post Share on other sites
