    looking at buying this car, mechanic informs me ZERO compression on cylinder 3 but cylinders 1,2 and 4 all show 150 psi, cars only done 58000 and is a 2004 plate. Looking for common faults i.e burnt value or blown head gasket. Any ideas will be greatly appreciated. Thanks

Are there any common causes of low compression on 1 cylinder ? the car has had a headgasket change done last year. I...

    Hi! I did a compression test on my Clio 1.2 8v, the results are the following: Dry: 190 180 200 200 Psi (gearbox this side) Wet: 300 270 270 300 Is this mean that all of my piston rings are worn? Isn't this a "little" extreme? I'm just curious because the dry tests are not bad at all, and...

    I was always told it's best to learn the hard way,,,,,, I was having a trouble getting the tdc on the meg 1.5dci, The pin was going in the tdc hole just before 12 or just after, i put it in just before, as when i tightened up the pulley clockwise any play would have gave me tdc. It took a while...

My car has done almost 108,000 miles and I'm wondering what compression it's lost. On a dry test, after 3 turns of the engine I got 12.5 bar (180 to 185 psi ) from...

    I have done a compression on my renault megane 1.4 2003 and I got 120 psi in cylinders 1 and 2 and 0 in 3 and 4 I think head gasket has gone between them but thought I would ask before I start taking the engine apart

    I want to carry out a compression test on my 1.9 dci prior to removing the head to determine which piston has low compression. I have done loads of compression tests on petrol engines but not on a dci. I have an adapter to fit the glow plug hole and will remove all four glow plugs and unplug...

    Hi, I bought a cheap 40 quid compression tester from ebay to do a test on a Clio 1.5 DCi engine. I have removed the glow plugs but have found the compression tester socket too short for me to screw into the glow plug hole!! I can only just get my fingers onto the end and screw it in a bit, but...

    I have only had my Scenic (2001 y reg) about 4 weeks and when my wife was driving down to Stansted Airport when the dreaded exhuast gas emissions warning light came on. A quick look up on here suggested probably a worn ignition coil. She limped the last couple of miles to the airport and on...
