My brother in law needs a cam plate bolt with an oil hole in it for a 360. Can we get it at a dodge dealer? Or do we have to order it from somewhere? Thanks, Bob
the new plate and bolt sets only come with 3 bolts, so that's what I used and the hole for the oil is left open.
Some engines came with a "tang" that bolted in behind the cam gear, on the upper right, and hung over with a little tab that went in the upper left hole (where the bolt with a hole usually is) and there was NO bolt in that hole.... The oil would come out of the hole, run down the "tang" and oil the chain.
Crazy, I have a picture of that in my Hanes manual but we don't have that 'tang' either.
that's correct scampy. 4 holes in the plate and 3 bolts. just left the one open that is drilled into the valley.
I double checked the mancini site, just to be sure I didn't get an incomplete package. but the picture for the kit does only show 3 bolts. I know of all the old set ups, but the new style just leaves the hole open. must be some new technology
If you get one of the new timing chain tensioners that replaces the thrust plate, It is only drilled for three bolts and has the dripper tab built in.
The write up about the timing chain tensioner indicated that the bolt wasn't available anymore and you were either down to living without the hole in the bolt (which is how newer ~late 70s+ 318/360s came), drilling your own, or finding a used bolt.
I just finished rebuilding a 1971 318 that was missing the upper left bolt drilled for lubrication. I used the oil tab (part # 3671649 shield 9023006)purchased from our local chrysler dealer.It's used on later model 318's. It cost $4.60,and bolted right in.
I used to use the bolt, I'd either drill one or use what i had.
But for years now I do not bother to drill the hola anymore and just leave that hole open.
