The Stovebolt Site Forums The Shop Area Engine Shop Oil Filter setup on later 235

Does anyone out there have a photo of the oil filter setup on a later model 235? Mine is out of a '61 Biscayne and the oil lines to the filter is what I'm looking for. When I got the block, it had an oil line running from the driver's side around to the head on the passenger side and no oil filter. I can't remember which block hole this line ran from. Looking at the driver's side, there are 2 threaded holes in what appears to be a lower oil gallery and 1 threaded hole above those in what appears to be an upper oil gallery (galley?). There is then 1 threaded hole below and forward just above the bottom of the block and slightly above the oil pan. (4 threaded holes in all and none are for the water drain as I have located that one). I'm planning to put the outlet oil filter line into that lower threaded hole that is forward and a "t" into the upper larger oil gallery hole mentioned above for the inlet hose to the filter and the oil gauge. Those two lower remaining holes appear to be in an oil gallery, but I'm not sure that is what it is. This sounds very confusing even to me. A photo of the set-up on a 235 of this model would really be helpful. I'm thinking I can use one of the lower remaining holes to run an external oil line around to the hole on the passenger side head and that will give it plenty of oil. Don't know if that is necessary or not. I've seen the posts here about the oil filter setup, but none are like my block. Can anyone help?

I don't have a pic to put up, but there should not be any lines running to the head at all. Sounds like the PO was trying to fix a blocked oil galley in the block. Instead of doing it right (clearing the passage) they just bypassed it. If the block has been hot tanked and the passages cleaned out, there shouldn't be a problem with the head getting oil for the rockers. As far as the lines on the block, there should be 2 holes for the oil. The rear one, just back from the throttle pivot, that should also have the "T" for the guage, is the pressure line comming out. There is also one toward the front of the engine, close to the pan rail. That is the return. It just dumps back into the pan. There is one other hole, towards the very back of the block, that one is the water drain. the other hole you see is most likely the mounting boss for a throttle pivot for a different application.
I'll see if I can get some good pix for you to look at.

Here's a photo of the oil filter setup on my '57 235. Hope it helps; if not let me know as I may have some other photos showing the install detail.

Here is a link to Dave Lindsay\'s inline 6 album. You should find something there to help you out.

thanks for the lindsay pix, they were gorgeous. ron

Thanks for the posts guys. I think I have it figured out. That bottom rail must not be an oil galley. Back when I first bought this block, I noticed that the cam shaft was oil starved and took the block in and had it boiled. The oil galleys were clogged bad. I've heard two different stories on that external oil line over the past couple of years. One is that the external line was a standard feature on late 50's-early 60's 235's. The other was that it was likely added because oil wasn't getting to the rockers and rather than fix the problem, the external line was added to pump oil north.

This article does a nice job of describing how the oil gets up to the top of the block in various years. Late blocks can get oil starved either by blockage or using the wrong lifters- even solid lifters need an annular ring to allow oil to flow to the head.
