[Amc-list] Popped the head off my 232...

[Tom Jennings <tomj@xxxxxxx>]

Finally got around to all the diags I meant to do LAST week. Plugs, 
compression check, etc, on the 232 in my Classic wagon.

FOr some foolish reason 15 years ago I started doing compression checks 
with all plugs in except the one under test, so I continued to do so. 
TOday I got it hot, pulled all the plugs, then checked. All the numbers 
went way up! Same guage.

most were 160, lowest 150 highest 170.

#1 wasn't contributing at an idle; this is with the Carter YF. With the 
CA125 LP carb, #6 wasn't contributing! But that's where the vacuum 
pickup was for the LP crap.

Looked in the oil filler cap, and the top end was pretty dry... this is 
one of those motors that feeds the rocker shaft up the head bolt 
passage... put an oil pressure gauge on the block, about 18 psi at idle, 
about 55 - 60 at 2500 - 3000 rpm, so that's not it. It sure used to have 
a lot of visible oil flowing over the rockers.

So I pulled the head. Maybe I could have just pulled the bolt and ground 
it and all that from Matt's page, but I was afraid of possible damage 
already done, and it has been on there 20 years this Fall.

It looks fine, but I dropped it off at the machine shop for a valve job. 
Should be just a "freshen up". Mild crud buildup in the head, some cyl 
wall crap above the rings. Absolutely zero scoring in the cylinder 
walls. 20 years of LP and most of that time on synthetic oil.


I also dropped off the aluminum intake I got from Joe to get boiled out; 
first come first served -- the Howell TBI kit will go on the Classic. No 
more carburetors!
