A few questions!!

[R1Dude]

Hello people, right I have just done a search and read up about compression testing, already cocked up on that one!! firstly ive used a standard tester, secondly engine was cold!! DOH!! the readings I got were 5.8 on both rotors! I seem to have confused myself (doesn`t take much!!) so I thought I would pick the brains of you guys!!

Question number 1. How far out could these readings be?

2. If I get hold of a rotory tester how does it read all 3 faces?

3. Is there anyone near Wolverhampton who would be able to help me in this situation? in exchange for cold hard cash and an apple!

4. Should I not drive her?

5. Would the comressions be higher or lower if engine is warmed up?

P.s I decided to do a compression test as I am losing water, temps hang around 85 degrees highest I have hit is 105 degrees. If I blast her I lose a lot of water out of the expansion tank, so I am stressing slightly

Thanx in advance Ade:Thumbs-up

Best bet is to take it up to WGT (Middlewich).  They charged me 1/2 hour labour (£30.00 tops IIRC) to do mine a couple of years ago.  They\'ll also tell you if the results are good or not.

You can use a standard compression meter if it has one of the \'release valve\' things on the side.

Basically, you need to remove the EGI fuse (to prevent fuel injection), then with the meter in one plug hole, hold the release valve in and crank the engine.

The readings will be hard to read accurately - you need to see what the peak pressure reading is as it rotates - should be 3 distinct peaks that you can descern.  These would be the 3 rotor chambers.  No way of knowing which one is which, only that one or more of them might be leaking or down on compression.  You need to do this for both front and rear rotors.

IIRC the test is usually made with a few hundred RPM on the clock - the more the better, but watch you don\'t flatten the battery.
