matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 Without wide open throttle . Just by turning engine over Quote
5e colin Posted August 6, 2015 Posted August 6, 2015 ya ok ish on the 3 but the 140 is right on the limit of rebuild time engine wont last very long before it wil need rebuild thats just my 2c Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 It's fairly even which is good. Would benefit from a rebuild as Colin has said. I'm guessing the engine may have done a fair few miles? Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 Yea what differnce does it make wide open throttle ? Around 85k miles Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 Shouldn't it be done with WOT?Yes it should.. I read it wrong.. I thought it said done on WOT. Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 Would it read high or low by not doing wide open throttle ? Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 You will have a low reading.. Your readings will be higher on WOT. Quote
Ollieh17 Posted August 6, 2015 Posted August 6, 2015 Slightly higher on WOT, was the engine warm? Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 It's mainly down to consistency over the four cylinders however a reading around 140 140 140 140 I would advise a rebuild. However a reading along the lines of 170 170 170 170 WOT would be great. Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 What use reckon then lads ? Still pulls like a train Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 What use reckon then lads ? Still pulls like a trainWithout WOT that's not too bad... I'd do it again at WOT when the engine is warm though for peace of mind Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 How much would it increase on wot ? Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 My mechanic said those reading are ok lol Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 Ive seen people saying them results with throttle closed is ok tho ?? Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 Ive seen people saying them results with throttle closed is ok tho ?? yeah they are mate ... its just supposed to be done at WOT with engine warm for true reading. Not saying there bad,,, They would be if the test was done at WOT when warm Quote
matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 U reckon b grand then mate ? Lol Quote
Matt1878 Posted August 6, 2015 Posted August 6, 2015 U reckon b grand then mate ? Lol Yeah, should be fine. Quote
H_D Posted August 6, 2015 Posted August 6, 2015 if you want a proper reading do it again and WOT warm engine and all spark plugs out.that's the proper way. Quote
Flaminsam Posted August 6, 2015 Posted August 6, 2015 You are mainly looking for a difference In pressure across all four cylinders. A pressure difference of 1 bar between the highest reading and the lowest reading would be your maximum. (Around 15psi) any more than that and it would be definite rebuild time. As Matt has said 140psi across all four is not bad with it being even. But you may find sooner or later you will have excessive blow by and need a rebuild. Healthy engines see around the 180psi mark.

matthew ep91 Posted August 6, 2015 Author Posted August 6, 2015 Is it an ok reading for no wot ? Quote
H_D Posted August 6, 2015 Posted August 6, 2015 I don't go by closed throttle figures so those numbers don't mean nothing to me.best to do a proper test to know how healthy your engine REALLY is. Quote
