Hi,

My brothers 62 Valiant may have a burnt valve. Soon we will do a compression test and find out for sure. The engine idles poorly and dies stopping at lights, that sort of thing.

If the valves are bad, I have a "parts car" with a supposedly newly rebuilt engine in it, which I would want to swap in. Both my brother's car and the parts car are 62 signets with automatics. The parts car looks to have a later style intake/exhaust which has me worried that it is a later engine.

My brothers engine numbers are:

10266
2463430-23
PT225R 21980673

Parts car:

072163
2463430-18
PT225H 21900542 (that is an H not an R).

Can anyone tell me if the engines will swap over easily? Bolt to the transmission?

Thanks!

John,

If the other engine is a 67-down, then it should swap in no problem.

You should definitely do a valve lash adjustment before you go further. The valves can tighten up over time and appear to be a burnt valve (low compression). I have done this "fix" a few times for others and it is nearly free (valve cover gasket only).

Best,

Lou

John,

I think both blocks were produced in 1966. Look here for casting number decoding.

Good deal guys, thank you.

I was thinking that doing the valve adjustment anyway after the compression check would be a good idea, and not just a waste of time and a gasket. It's nice to have the idea confirmed!

I was hoping that Dan would chime in with a date decode :D . Also, I'd like to know what the top number on the side of the block is, I couldn't find it yesterday in my reading of the forum and elsewhere.

No need to swap engines, the compression check was fine and the valves in three cylinders were badly out of adjustment.

Thanks again for the replies!

Glad to hear it was a simple fix! Enjoy the drive...

If it was the exhaust valves that were too tight, you need to be using a lead substitute additive in the fuel. You'll find it at the auto parts store. The exhaust valve seats are not hardened, and the lack of lead to lubricate them results in wear, with the valves receding into the head.
