I have a 1991 Jetta and I am wondering what the engine code is or how I can find out. Here are the details:
- bought in Canada
- 8 valve gas engine
- made in Wolfsberg (VIN starts with WVW . . .)
The reason I am asking is that I have located a couple of mass air flow meters online, but in order to pick the right one I need to know whether my engive code is "PF" or "RV".
Many thanks in advance.
I'm 98% sure that the only difference between PF and RV engines are the exhaust systems; one has the dual-outlet manifold and downpipe (stock w/105 bhp) and the other has the piece-of-junk toilet-bowl-style single-outlet manifold and downpipe (stock w/100 bhp and a pair of super-annoying clamps attempting to hold the exhaust system together). So either should work.
I have the piece-o-junk single outlet with those two stupid "C" clips. I have hated them since time immemorial.
Thanks for your help.
Cheers.
Should be RV. PF was on the Carat only.
you definitely have RV then.
shouldn't make a difference though for the MAF. The only thing that I know of that would affect one MAF vs. another is the Digifant I vs. Digifant II systems and Digifant I was on California-only 1991-1991 8V gas 1.8L Golfs/GTIs/Jettas with RV engines.
Not true my '91 California Wolfsburg edition is a PF.
Original engine and not a transplant? Odd...should be a RV.
It's stamped on the engine block. On my Canadian-spec
1986 Jetta it's MZ - 1.8l SOHC engine, CIS injection, no cat, big filler neck for leaded gas.Hardly even broke a sweat at 105 klicks (4000 RPM in
4th gear) going up through the snowshed on the Coqui- halla Highway a few weeks ago. Not bad for old technology with 270,000 km on it. :-)Laura Halliday VE7LDH "Que les nuages soient notre Grid: CN89lg pied a terre..." ICBM: 49 16.57 N 123 0.24 W - Hospital/Shafte
Good choice. I did that. a bit of a pain but worth the effort.
