Compression Test 156K
Volvo V70 1999 NA Denso
Engine model: B5244S 2435cc

Code P0300

Using Gunson's compression gauge.

Dry Cold
Open Throttle (ETM wedged open)
Cranked 8 x revolutions
No plugs present to Other Cyls
Injectors unplugged.

Cyl 01 = 215
Cyl 02 = 188
Cyl 03 = 204
Cyl 04 = 212
Cyl 05 = 070

Wet Cold
Open Throttle (ETM wedged open)
Cranked 8 x revolutions
No plugs present to Other Cyls
Injectors unplugged.

Cyl 01 = 240
Cyl 02 = 240
Cyl 03 = 220
Cyl 04 = 245
Cyl 05 = 090

I didn't bother to do 'hot dry' or 'hot wet' runs, what with Cyl No.5 as it is, I know enough. Reckon the head must come off. It still limps on. I'll drive it a while longer. Was giving code P0300, and likely still will next outing This is a car I've recently acquired with a truly lousy LPG install. It conforms to all the stereotypes that LPG became famous for. Holy Scotchlok, sadly, back in the day, so many cars were bash-up conversions, and the reputation of LPG went south.

I remember the ads.... "£1200 and collect next day!"

Clearly, this one was 'thrown-in' under a railway-arch on a wet Tuesday. Customer wanted it cheap, that's what it is.

In short on NA cars, this with 156K on the odometer, 'dry' expect to see 215 on a good pot. Turbo are lower.

And...

Cylinder 1 is nearest the cam-pulley, ie: on the RHS of the car from a driver's perspective. Cylinder 5 nearest battery-tray, to the LHS of the car from a driver's perspective.
