L-series valve cover height

[jovial_cynic]

Jeff/Icehouse mentioned a while back that the L16 valve covers are shorter than the L18/L20b valve covers. Can anybody confirm this? If it's true, does anybody have an L16 valve cover they don't need?

[datsunaholic]

I don't think they're any different- the cam towers and chain sprocket are the same size. The difference between the L16 and L20B is the BLOCK, hence the TIMING covers are shorter.

 

Of course, I don't have any of the really, really old ones to compare, just the 1970-on ones.

That's what I thought... but I'd still like to confirm.

 

Incidentally, I'm not using the stock engine mounts; I'm using a Z-block, and I had the mounts in there that held a NAPS-Z motor in the bay... but that engine sits more upright than the L-series mounts. That's the actual problem. Maybe I should see if anybody has any stock 510 engine mounts. That might be a better solution.

I don't remember saying that.... the blocks are different I don't know about the valve covers. Are you sure I wasn't talking about the ka de head? That would make the shortest engine. Hhhmmm how long ago was it I said that?

[jovial_cynic]

haha... well if the source can't confirm it, I guess I'll throw it into the internet rumor pile. :: shrug ::

 

It was a couple of months back, over e-mail. It's possible that I was talking about valve covers, and you heard front-cover, and answered the wrong question...

I had one that I shipped to canada...seemed it was exactly the same size

[jovial_cynic]

Yeah - I think I may have had a communication error with Jeff. Anyhow, I made some custom engine mount brackets to lower the engine in the bay, and that takes care of the problem.

This is from your favorite buddy: ME

 

I believe they are exactly the same but I do have one cover that is a cunt hair short when No gasket is installed. But then relieved I have 2 cam tower shims on ther and maybe the baffle is hung lower on this valve cover.

 

I have heard people slotting the engin mounts to lower the motor abit if the valve cover is hitting the hood. But never actualy seen this myself

[hang_510]

no diff in cover heights.

all L and Z motor combos should clear EXCEPT an LZ24, which requires a lump in the hood.

mine has it and the 2 others ive seen also have it.

 

if it doesnt become cliche too soon, im gonna make it the sun in a rising sun scheme.

I slotted my engine mounts to drop my engine down. I know you can do this with a 2.4. There is a guy in Salem with a LZ2.4 in a '68 wagon. You have to look close to even notice. They sectioned the oil pan and re-worked the engine mounts to get it to sit like a stock L16.

In any event, cutting and welding my own mount brackets solved the problem. No worries here. Nothing a welder and some 1/4" metal can't solve.
