Turbo Goose Posted November 4, 2014 Share Posted November 4, 2014 (edited) Hi guys, Today is not a good day..... I'll explain,So the other day I was driving back from work when I came across a row of slow moving vehicles. In my ignorance I thought I'd overtake these cars a piece of cake and be on my merry way. I dropped her down a couple of cogs and gave her some sugar, I got about mid way past the cars when I felt a splutter but I kept my toe in, looked down and saw the engine management light. Little did I know at this point the car had boosted to 2.6 bar! I resorted to driving like a grandma and the very row of cars I had just overtaken, one by one, overtook me.So I limped her home, checked the fault and it came up with knock sensor so I changed that which solved the engine management problem.Started the car up took her for a spin still not realising the vac pipe had come off the wastegate, give her some beans and looks at my boost gauage straight away which popped round off the scale. I obviously limped her home again. I've started her up a few times since and shes lumpy on idle. I purchased a compression tester and it came up as, wait for it....45psi - 50 psi - 0 psi - 50 psi?? Either I'm retarded, the compression testers dodgey or my engine is seriously fucked??? I've done each cylinder a couple of times and even got third party help from my brother and we get the same results each time! Anywho, pretty sure my engines knackered. The spec is TF035 @1.1bar mapped on emanage blue. Been running a treat up until the other day and I think the boost pipe popped off whilst I was passing them cars and my boost controller (not currently connected to a solenoid) read a max of 2.6bar!Also the fault sensor thing confused me? And is it possible to get such low readings across all 4 and even a 0 on one of the cylinders?? Edited November 4, 2014 by Haresign Quote Link to post Share on other sites
Ollieh17 Posted November 4, 2014 Share Posted November 4, 2014 2.6 bar!! Did it go well? Quote Link to post Share on other sites
TrisK Posted November 4, 2014 Share Posted November 4, 2014 Sounds like some serious piston/ring damageAlthough I'm suprised that it would run and drive with figures that low Quote Link to post Share on other sites
Turbo Goose Posted November 4, 2014 Author Share Posted November 4, 2014 Same here, It starts up fine but very lumpy moving it on the drive. Also poops lots of oil splatter out the exhaust And ollie suprising not lol, just spluttered and missed Quote Link to post Share on other sites
5e colin Posted November 4, 2014 Share Posted November 4, 2014 2.6 bar!! Did it go well? really wel ha ha back to op sounds like dodgy tester 45 is REAL LOW when you open her get measuring tools to check your rods because i think they will be warped now !!! Quote Link to post Share on other sites
Turbo Goose Posted November 4, 2014 Author Share Posted November 4, 2014 I'd like to try another tester or another car tbh but everyone in my family has diesels Quote Link to post Share on other sites
_shaun_ Posted November 4, 2014 Share Posted November 4, 2014 That's impressively low. Are you doing it full throttle and warm. Make sure your battery's got a good charge in it. And how long did u turn the key for! Shame the damage a single vac line can do. Quote Link to post Share on other sites
mikey4410 Posted November 4, 2014 Share Posted November 4, 2014 yeah makesure engines up to temp, throttles wide open and u do 5 sec burst on the key. Quote Link to post Share on other sites
Bluebear Posted November 4, 2014 Share Posted November 4, 2014 Would the turbo have been over-speeding massively as well due to that boost pressure? Could have knackered the tubby Quote Link to post Share on other sites
Socks Posted November 4, 2014 Share Posted November 4, 2014 Blown Piston 3.... Overboosting. Knock Sensor tried to pull the timing out, but couldn't do it enough... Hence failure... Quote Link to post Share on other sites
patman Posted November 4, 2014 Share Posted November 4, 2014 On a compression test isn't there a thing where you put oil (not sure how much) down each spark plug hole (plugs out obviously) (one at a time) and if you get a much higher reading then before your rings are shot? Can anyone confirm this to help him know for sure 👍 Quote Link to post Share on other sites
Turbo Goose Posted November 5, 2014 Author Share Posted November 5, 2014 Think the connection on the compression tester is a bit shabby. Going to try another one from work but pretty sure piston/rings 2nd from right of engine has had it Quote Link to post Share on other sites
WallaceGlanza Posted November 5, 2014 Share Posted November 5, 2014 If you've got 0 compression in one cylinder and its running lumpy you've pretty much definitely cracked a piston. Quote Link to post Share on other sites
funny onion Posted November 5, 2014 Share Posted November 5, 2014 Sounds like mine... and the result of that wasn't good :/ mine had 0 compression on 3 and 4 and about 50psi on 1 and 2. very lumpy idle (obviously) and oil/smoke pistons and rings had melted horrendously on 3 and 4 and started to go on 1 and 2. That was about a month after a £670 emanage and remap, but I will say no more on that matter Quote Link to post Share on other sites
Bussey Posted November 5, 2014 Share Posted November 5, 2014 2.6 bar! I'm surprised you didn't blow a hole in the block and the head didn't jump off! Quote Link to post Share on other sites
Socks Posted November 5, 2014 Share Posted November 5, 2014 Take your dipstick out. Doesn't blue smoke puff out of it?I really wouldn't bother trying to test anything dude. It's gonna want a bottom end rebuild. Or a replacement engine. You can't run boost like that and get away with it. Quote Link to post Share on other sites
Turbo Goose Posted November 5, 2014 Author Share Posted November 5, 2014 If it needs new engine I'm just going forged and I'm 99% sure it does. Be interesting to strip the engine down just to see whats occured! Quote Link to post Share on other sites
Socks Posted November 5, 2014 Share Posted November 5, 2014 Im sure your tuner will tell u/show u exactly whats happened. Perfect engine to be forged tbh! If the bottom end/crank is all good and within spec. Re-bore will get rid of any markings on bores from piston failure! Perfect Winter job! Quote Link to post Share on other sites
Socks Posted November 5, 2014 Share Posted November 5, 2014 TF035 will go up to 260-270bhp all day long... Quote Link to post Share on other sites
Starbuck Posted November 5, 2014 Share Posted November 5, 2014 Sounds like mine... and the result of that wasn't good :/ mine had 0 compression on 3 and 4 and about 50psi on 1 and 2. very lumpy idle (obviously) and oil/smoke pistons and rings had melted horrendously on 3 and 4 and started to go on 1 and 2. That was about a month after a £670 emanage and remap, but I will say no more on that ma I hear you Charl..... . Sorry to hear of the trouble HS Quote Link to post Share on other sites
Turbo Goose Posted November 5, 2014 Author Share Posted November 5, 2014 I personally can't see there being an issue bottom end as it was only at 2.6 bar for a matter of seconds so just imagine its ruined the rings and/or piston.Unless extra boost pressure could cause bottom end failure but I thought that was caused by oil starvation?

TimD Posted November 5, 2014 Share Posted November 5, 2014 Compression tester must be working a little bit if you're getting a reading, so I would imagine you have damaged piston/ring/ringland on cylinder 3. Hope you get it sorted soon! Quote Link to post Share on other sites

Unless extra boost pressure could cause bottom end failure but I thought that was caused by oil starvation? If you have a cracked piston or ring... Blue SMoke will puff out the dipstick tube when you remove the dipstick... It will be misfiring on that cylinder too.. IE if you remove the HT lead to that cylinder the engine will not change how it runs... Quote Link to post Share on other sites
