Compression test result question 200 92

posted by  someone claiming to be Jorn Schreurs on  Mon Jul 9 23:36 CST 2001 [RELATED]

Yesterday I did a compression test on my 92 240 wagon (150kmiles). This is European (England) car with a B200F engine. The B200F is 1.99ltr and therefor benifits from lower tax in most European countries. I don't think it has been used in the US. Is is bascially a B230F with different bore, stroke etc. To get some sort of power out of it (still 111hp) the compression is supposed to be higher.

However when I tested the compression I got 14 bar (203 psi!) out of each cylinder (at least in balance, spot on in fact). Personally I thought that was a bit high.

I did the compression test with warm engine, no sparks, open throttle, dead fuel pump etc.

The plugs and engine timing show no signs of carbon build up, in fact the engine runs great giving 28 USGAL/mile average use, no rattling or knocking.

Does anybody have an insight in the B200F design and the compression details of this engine. Haynes remains vague on the B200F and the instruction manual only gives the compression ratio 1:10.2

Many thanks,
