[Es2] Valve guide question

[Mark Wetzel]

I'll ask around. I know when my head was done, the wrong guides were
used, and it was blowing a ton of oil, and had to be redone. I'll ask
the guy who did my motor what he nows.

Subject: [Es2] Valve guide question


I've got the head out for rebuild from my 200q20v engine donor and my
machinist is having problems with the valve guides.  He says that from
the shoulder to where they step down, the length needs to be ~.450" or
11mm, and the guides that I bought are ~.330" or 8.5mm.  These
measurements are from the guides that came out of the head versus the
new ones I provided him with.

The worldpac sites mention both 8.5 and 11mm guides under the part
number 027 103 419, but they only seem to stock the 8.5mm ones.
Autohausaz and Rod at TPC can't get the 11mm guides, something about
them being discontinued or dealer only now, maybe.  Rod said something
about the 11mm guide being for a head that's been redone before and that
the head may have been machined to take the longer stepped down portion
guides.

My machinist says he can mod the guides so that they'll fit, and I'm
thinking of having him do just that.  Did the 200q20v come with these
different guides, were they installed during a previous head rebuild,
should I try to find the 11mm guides, or just have the machinist
change/machine them to fit?

Any other BTDT?

Thanks!
