Sorry Ive tried searching but with no luck so hope you can help

 

As above can i do a compession test on a engine while its out of the car? having read on the net i believe i could do a leak down test but only have the compresion tester available to me at this time

 

thanks in advance

Yes you can, you'll need a gearbox attached so you can fit a starter motor.

Thanks for the reply Tom,

 

would you then put battery straight to the starter to turn it over and get results

 

thanks again

Thats pretty much it yes. Normally you would comp test an engine when hot, so bear in mind that the results might be slightly lower than you'd expect as the engine is cold.

Hi Tom, I was having a chat about this today at work and thought id see what you or others thought,

 

1) Is it possible to do build enough compession to test by just turning over the crank by hand (with bar and socket), i was`nt sure about this but sat there politely

2) I was asked why i needed to put a gear box on to do this and thought id just ask to confirm

 

Is there such a thing as a tea room mechanic, there seems to be at my work, Id rather take advice from people i know have done this or know for fact unlike these two i have to call work colleagues

 

thanks

Gear box needed to bolt starter to!

 

Plenty of tea room mechanics, have 2 in my office. One is a girl who claims to be able to "service and maintain" any car - including her car that just failed MOT on headlight alignment, which she then paid the garage to sort...

1, I doubt it, would be bloody hard work if you tried

 

2, The starter motor bolts to the gearbox's bellhousing on an XU engine, hence the need to bolt a gearbox on.

 

 

If the starter bolted to the engine then you could do without a gearbox, this is quite rare in my experience though, only one I remember coming across happens to be a Peugeot/Renault V6, makes gearbox changes a little easier

Thanks for all the advice i dont know how i mist that thread surgie but thanks for bringing it to my attention, Ill have a read later

 

completly forgot the starter bolted to the box and one of the tea room boys were telling me blind it went on the block cheers to them for nothing

 

thanks again,

Gary
