building my L24.

Featured Replies

Finally took it upon myself to rebuild my 1970 240z L24 engine. Nothing too wild. Went .20 over, installed new seats, valves, springs, bearings, ARP head studs, main studs, rod bolts and clutch bolts (yes. overkill, But I want to trust the engine). 

Finishing up gapping the rings, and installing them. Bearings and crank should be installed by the end of this weekend. 

The Datsoon marches on.

More to come as it all comes along. 

What pistons and rings did you use?

Stock cam?

What valves- stock size?

Stock cam, Stock valve size. Pistons came from ITM. Nothing crazy, just a overbuilt factory rebuild. 

Not my first time building a engine, just first time building one for myself. I'm doing as much as I can to get it built quick and back on the road as soon as possible. But not skipping anything and taking time. This weekend im cleaning surfaces and polishing parts. Hope to have the pistons in the block by mid week. 

Are you using the ITM rings or something else? If ITM, how do they look to you? Are they chrome, Moly, or iron?

Well, Went around to gapping rings, and installing bearings today. Cleaned everything then installed bearings, coating them in redline assy. lube. Then took about to painting the block. Laid down multiple coats of a primer with ceramic in it. Once that had dried laid down coats of Datusn engine paint, sourced from Datsun parts. 

Turned out looking great, if I do say so myself.

I'm not sure who made the rings, but I have to assume ITM. If i understand correctly, chrome top cast 2nd.
