compression

Hi all, Need a bit of help. Had an exhaust leak so took the downpipe off from the manifold. Found a 2nd hand manifold in a scrapyard. Bought new springs and bolts. When going to put it all back the springs are too long. The old springs are slightly shorter (I assume as they have been...

Hi. Has anyone built a high compression engine for a 21T? My goal is just over 200-225bhp and low lag. The engine is completely in bits so now would be a good time to change things around. An engine builder I spoke to recommended to build it as an NA but keeping the turbo cam and valves. The...

Would anyone have info of the compression height and the height of that slightly raised area of the standard gtt piston? Also the distance between the edge of the piston and the highest piston ring grove is interresting. They doo seam a bit lower than that from the Alpine turbo and also have...

What did Renault do to drop the compression ?

Has anyone got a view on these, as they seem to throw up huge pro's and con's debates.I've read about it being a bodge,whilst others have run huge boost through them for '000's of miles with no problem whatsoever.

Could be a daft question but I could really do with compression testing the replacement engine I've bought for the Vectra. I've looked at a couple of kits, but the all seem to require the engine to be turned over on the starter, which I can't do with the engine being stood on the garage...

i compression tested my f7p ,what should it it read ?

Right did a compression test today so can anyone tell me what the tollerances for compression between each cylinder??

can anyone tell me if these compression test results are normal dry test no 1=176 no2=174 no3=188 no4=180 wet test no1=188 no2=180 no3=194 no4=192 i think my rings have gone because it smokes when i rev it, but as i have not done a...

anyone got the tools for doing one for us? i can drive to you, just need to confirm something, lol

Going to be re-assembling my williams engine soon and get the hybrid on the road. Is there a way to make sure the compression readings will be good or will i only be able to find out once the engines back together? Theres nothing to suggest they would be bad its just me worrying and not wanting...

just done a compression on my valer and all four borse were at 180 is that good or bad as its only done 72400 miles

Hi all. I have successfully rebuilt the top end of my engine following a cambelt snap. It is all running smoothly and has been for about a month (thanks to the help on this forum). I thought that I would give it a quick compression test to see if it is all good. What value should I be looking...

Hi I was just wondering if you know how to fix the compression problem that I have,I have just put the williams bottom end on my clio with the 1.8 16v head. I have put the williams cams in it as well,i have tried to start it and I have no compression at all,could this be head gaskett with it...

Can anyone please advise how you check the valve timing on a 1.8 16v clio? It's a 1992 model; and has just had the engine replaced - but is lacking power when you open the throttle fully; you get the deep induction noise it's just go no ooomph! :cry: Also can you please confirm what reading...

Hi all, Anyone no where the fuel pump relay or fuse is?? Need to do a compression test but dont want any fuel going in and flood it!! Also does the engine need to be warm or cold to do a compression test. I was told cold from a reliable source but the compression test kit i just brought...

Does anyone know the standard compression ratio for these cars and the skimming tolerances for the head as i got a recond head when i bought th car(look brand new) and has had a skim but i dont no wheather it is skimmed 2 much etc. :?

im wondering of any 1 has any ideas, i keep losing compression on cylinders 1 and 2, more on number 1, i've checked all the stuff i can, i even thought about it being bore wash from the chipped ecu but have tryed another ecu on it, Cheers Ben
