Few updates for ratsun. Had a great new year only to be followed by icepocalypse the week after. Movement has been at a crawl due to weather but here goes. Tore into the head only to find the valves were seized and completely fouled. My cams had surface rust plus some deep seated rust on the rockers. My cylinders were swimming pools. At first I started to think that a rebuild was going to be the best option, but then I scraped my old head gasket off and kept feeling a raised surface between cyl 2 and 3. Inspected it further and found a crack between exhaust ports and water channel.

I'll snap some pictures of what they look like as sitting when i get a chance. I shot them with some flat black rustoleium with rust inhibitor to make me feel better but I'll look into the por15 and zero rust options. Thanks for the tips.

Here is a glimpse into my last couple weeks. Pounding out the devils tar paper with about 30lbs of dry ice. I'd recommend this technique to anyone wanting to strip cabin down. I ran into a good amount of rust on the floor panels. I've heard of a guy on the east coast that sells panels for pretty expensive. I'm just going to ignore it until it gets annoying. Seems like the rust is being caused by a small gap in the windshield gasket. Bought some flowable silacone to patch it until winters done (Oregon winters are no joke in terms of moisture). Adding to the list of small purchases, I had to rekey the ignition cylinder because I lost the one and only orignial.To do this I had to pull the passenger side lock cylinder and had a key matched. When I put the brand new key inside the ignition to turn it something happened (my guess is that it sheered some of the wafers on the inside). All said and done about 2 days and 30$ later I had a new ignition cylinder with brand spanken new keys and 2 door locks with their own set of keys.

I've seen h2theizzo's "L-series head gasket" replacement videos about 45 times. I made a wedge block of wood from someone's build thread on here . Thanks for the tip, seems like dropping the tensioner = the end of the world.

My first and current Datsun. '76 620

Picked up my first Datsun a little while ago. Long time forum lurker and excited to finally have a build on here. Details Location (Portland, Oregon) 1976 620 L20b 4-speed manual Currently it has a blown head gasket and (hopefully) minor wiring issues. I've been soldering up a 30/40 Bosch "hot start relay" to replace a faulty ford 4-post style relay. The head gasket gets done this week sometime. Hopefully you guys enjoy Dotty as much as I do.
