Dataholic Posted September 14, 2011 Report Share Posted September 14, 2011 Alright guys big noob here. I'm changing the head gasket on my L20b and I've taken off the carb and am trying to take off the intake and exhaust manifolds. I'm used to small block chevy's and this is proving to be difficult for my rather large clumsy hands. I've unscrewed 4 bolts from the intake manifold and 4 bolts for the exhaust manifold, and neither seem to be loosening up from the head, can someone help me locate where the other bolts are that need to come out. Thanks for the help. 1 Quote Link to comment
hobbes_the_cat Posted September 14, 2011 Report Share Posted September 14, 2011 There are i think 4 more between the intake and exhaust manifolds. the have big washers on them and they hold the intake and exhaust with the same bolt. you will need some extensions and a knuckle to get to them. it is a pain.

datzenmike Posted September 14, 2011 Report Share Posted September 14, 2011 Take the head off with the manifolds attached. YOU KNOW TO LOCK THE TIMING CHAIN BEFORE TRYING TO REMOVE THE CAM SPROCKET? IF NOT, SAY SO AND FIND OUT WHAT TO DO OR A 3 HOUR JOB WILL EXPAND TO DAY LONG OR WORSE. Quote Link to comment

Dataholic Posted September 14, 2011 Author Report Share Posted September 14, 2011 Sweet lots of help, while pulling everything apart I noticed three thin plates separating the exhaust manifold, the intake manifold and the carburetor. Do these serve any purpose, I know one holds the air breather in place but I can't see any other reason for them being there. Since it is already cramped in those areas I'm debating leaving them off when I put everything back together. Quote Link to comment
banzai510(hainz) Posted September 14, 2011 Report Share Posted September 14, 2011 take a photo. I forgot what the later L20s have on there Quote Link to comment
ZackTheImpaler Posted September 15, 2011 Report Share Posted September 15, 2011 Yeah always put up a photo of what you are talking about,it'll get a quicker answer. When taking off the manifolds those little wobbly u-joint things for sockets are your best friend. Quote Link to comment
Buzzbomb Posted September 16, 2011 Report Share Posted September 16, 2011 Go to Sears and get a 12mm swivel socket with a shallow end. WHen you get that, do a search and find a side view picture of the manifolds. You'll see which ones you are not getting, and then you can get them "by feel". I used the said socket and I THINK a 12 inch extension from the bottom or side, and it turned what seemed a near impossible job into a 5 minute job. Quote Link to comment
