17yostagea Posted February 14, 2011 Share Posted February 14, 2011 (edited) Hi all was driving home work tonight cruising along and my S1 25g with stock N/A RB25de started to run very sluggish s0o pull over switch her off but she will not start, got power, faul pump and starter goes got comprestion,inject pulse and spark but wont start.

Duncan Posted February 14, 2011 Share Posted February 14, 2011 lol, grog? anyway, agreed...how did you determine you have fuel and spark? Do you have a big air leak in the intake piping (split or blown hose after the AFM?)

Duncan Posted February 15, 2011 Share Posted February 15, 2011 right....well then you already know it is likely to be bad then. the only rb know for sure is non interferance is rb20. if rb25det is interferance and rb25de has higher compression....it is very unlikely to be OK.

wolverine Posted February 15, 2011 Share Posted February 15, 2011 Come on Duncan don't be a spoil sport, I am pretty sure JP showed you the timing belt that came off my R33 when the idler bearing seized and stripped the timing belt. New belt fitted, it started and purred like a kitten. I have no chance of winning Powerball now.

RS4-S Posted February 15, 2011 Share Posted February 15, 2011 how old is the belt? if you recently replaced it, what brand was it? i believe RB30's are also a free spinning/ non-interference engine, wasnt 100% with 25's but now i know Link to comment https://www.sau.com.au/forums/topic/353943-stagea-brake-down/#findComment-5672116 Share on other sites More sharing options...
Duncan Posted February 15, 2011 Share Posted February 15, 2011 yeah 25det and 26dett definately are interferance. Not really surprised rb30e is non, I wonder what a hybrid rb30det is, pretty likely it will be interferance? Andrew....damn straight you have used up all your luck!

wolverine Posted February 15, 2011 Share Posted February 15, 2011 could be onto something there iv got a new belt to fit tomoz what esle u do to it just the belt?? and away u went? The mechanics expected they were going to take the head off but figured it was worth trying to fit a belt and idler bearings and then turn it over by hand to see what would happen. It turned ok, so they cranked it and it started like normal. There is no joy in getting the bill for a new timing belt (etc) but in this case it beats the hell out of a new engine.

rb30dett Posted February 15, 2011 Share Posted February 15, 2011 I have seen teeth stripped off the belt before and every time the belt had been subjected to engine oil leaking on it. Look for oil leaks and check bearings I would like to know what caused the belt to break.
