350 Timing Cover

    I have a NOS (2004) timing cover purchase for I believe a 68 wagon with a Buick 350.

    It's my understanding I can use it for my 225. However, IIRC there was a poster recently saying the 350 timing cover would need modifications to fit a 225, but can't find the post or what the mods were if any.

    jpflat2a what's that noise?

    The Jeep parts manual shows the same p/n for both uses: 991689
    That p/n may have changed later down the road.
    The issue might be whether the timing marks are embossed into the cover or a bolt on
    timing indicator had to be used.
    Memory too fuzzy.....

    There were 2 different timing covers used on the 225, an early and later one. The early one had 2 bolts missing on the sides of the upper water passages. The early blocks are not tapped for these holes and the gaskets are different. I would bet the 350 timing cover has the extra 2 bolts in it like the later 225's. But the timing marks are also probably different.

    Purchased 2004? as I think Buick quit making the 350 about 1980.............and I believe the timing marks in that cover are off something like 11 +/- degrees vs the 225........that info is definitely in the Wayback machine.

    Should have said new aftermarket purchased by someone in 2004.
    Just pulled it off the top shelve in my parts room to look it over.
    Jim, yes no timing marks on the cover.
    Mike, yes on the 350 cover fitting the later 225.

    I have all the bolts out but one. The left side of the water pump (long bolt). It is flexing a bit and feels like it will break if I push it. I don't want to use heat near the aluminum so I think I'll grind down the head so I have something to work with unless someone has a better idea.

    Oh yea.
    Mike is right.
    There were two different gaskets for covers on the V6.

    I think the timing cover pictured interchanges with the 231 V6 even-fire from the 1980's, as used on a Regal, but not the 225 odd-fire. Look at the pan rail shape. This one is "pointed" vs the 225 one is flat across the timing cover.

    Chuck - let me know if you need me to find it for sure, but I believe it's 18* difference. I have a 350 cover on my Kenne Bell motor. I cut a new timing mark on the crank for mine to use.

    Thanks for the offer Chuck!
    I did remove the old cover, I got all the bolts out but one. The bolt was bonded to the timing cover. I was able to move the cover away enough to cut the bolt between the cover and block. I was then able to use locking pliers to remove the short piece of bolt from the block.
    I've been busy with family commitments and haven't been back in the shop however, I will know for sure this weekend and post up.

    Have you been back east since we sat down for a beer?

    I'll be using the original cover as it is in pretty good shape.
    Donny, the 350 cover that is pointed at the pan rail matches up with the oil pan bolt holes so it can be used on the 225.

    Not much back to the Mass area. I changed companies @ 5 years ago and back east for me now is the Atlanta area about 6 - 8 times a year and the UK a couple... trying to avoid India and Sydney for the other trips.

    I have a quick question that I rather not start a new thread on. I found an o-ring under the CJ, 1" inside diameter. A replacement is in the timing cover gasket kit, nothing on the diagram that I see. Where would it go?
    I'm ready to button this job up so I'll keep looking for its home.

    Has to be the distributor o-ring. I have one on my distributor when I pulled it so I'm thinking a PO dropped one down the distributor hole and it sat at the bottom of the timing cover and dropped out when I removed the cover.

    Good to know. I'm suprised they interchange as they look different extenally.

    The bottom section of the point is solid so it can be used for multiple engines. It also comes with 2 front pan gaskets, one pointed, and one straight like the 225.
