russaroll Posted July 22, 2023 Report Share Posted July 22, 2023 Ran into a bit of a problem today. I was trying to get my engine back together and, wouldn't you know it, I seem to have the wrong timing cover. As you can see it IS for an L20B. Anyone have the one I need, with the bolt holes farther apart? I will trade you or buy if I have to. L20b U67 Thanks Quote Link to comment
banzai510(hainz) Posted July 22, 2023 Report Share Posted July 22, 2023 (edited) WTF???? a L Head should still should be the same spacing for the timing cover. Maybe Im missing something on this one Is that a Z series front cover???? Edited July 22, 2023 by banzai510(hainz) Quote Link to comment
datzenmike Posted July 22, 2023 Report Share Posted July 22, 2023 That's a Z20 or Z22 timing cover. 1 Quote Link to comment
Stoffregen Motorsports Posted July 22, 2023 Report Share Posted July 22, 2023 Take the cover back off and have those areas welded up. Then sand it flat and drill/tap new holes. When L20B covers became hard to find, this was the solution. Quote Link to comment

If worst comes to worst, I might have to. that's the last time i buy from FB. Edited July 22, 2023 by russaroll 1 Quote Link to comment
datzenmike Posted July 22, 2023 Report Share Posted July 22, 2023 Actually the L head does seal against a Z timing cover. There is one spot front right corner that is thin but a little JB Weld and a file fixes this. In this instance it's an L head on a Z block using a Z head gasket. Can't use any bolts but this area doesn't have to deal in anything but fumes and oil splash from the chain. Maybe a little RTV smeared on the front and two sides. Quote Link to comment
Stoffregen Motorsports Posted July 23, 2023 Report Share Posted July 23, 2023 RTV won't hold it. I've tried and they eventually leak. Quote Link to comment
datzenmike Posted July 23, 2023 Report Share Posted July 23, 2023 Well not just RTV but on both sides of the gasket. The head bolts should clamp it against the timing cover. Goes without saying that it should be de-greased thoroughly. If not RTV then a sealer like for differentials and transmission cases might be better. 1 Quote Link to comment
RetroRocket Posted July 23, 2023 Report Share Posted July 23, 2023 Find an L20B timing cover and be done with it. Maybe someone will pay it forward and give you one. Quote Link to comment
banzai510(hainz) Posted July 24, 2023 Report Share Posted July 24, 2023 Lots of covers still out there Quote Link to comment
