Here's why I so busy at the moment

Installing new liners

by **Yarno** » Sun May 24, 2009 4:18 pm

Installing crank, new bearings..

Oil squirters, two were totally blocked, had to clean them out.

by **Yarno** » Sun May 24, 2009 4:20 pm

New pistons and rings going into the new liners, new small end bearings (these had to be reamed as they are un unfinished size)

by **Yarno** » Sun May 24, 2009 4:22 pm

Checking deck height to make sure the head gasket is the right thickness.

what did you use for a timing cover gasket?

by **Yarno** » Mon May 25, 2009 7:21 am

It came in the kit, as the kits you buy are for belt and gears. The only thing that hasn't been in the kit so far is the o-ring for the cam shaft seal retainer, which is a 50mm x 2.5mm and diesel pump gasket which I just made. The kit I got from Roodogs on eBay, it had new pistons, liners, bearings, full gasket and seal kits, sealant, and basic setting chart.

The rebuild kit i got was for a gear drive only. I had to get a camshaft seal and T/cover gasket

It might be a bit late, but the liners are much easier to get in, less likely to be deformed and/or scratched if you put them in a Freezer (in bag to keep out moisture) or use dry ice.... just push in, with maybe a light tap at the end. :-)

Don't worry they went in easy, I had the block in the hot wash for about 3 hours to get the dirt off before I pushed them in, I worked out on the last two that I just needed to slide em in then a little tap with the soft hammer and they were in.

Cool, the warm block must have made it easier :-)

Did up the head this weekend, all this has been very time consuming.

Very clagged up

by **Yarno** » Sun May 31, 2009 8:07 pm

Found two of the inlet valves were bent.

Grade 3 head gasket

tensioned

rocker gear and push rods in

by **Yarno** » Sun May 31, 2009 8:15 pm

The intake plenum on this was heavily caked with oil gum, this was from the blown engine which would have been in good condition before it went for a swim, the valves were in the same engine... I tried everything to get it out, degreaser, burning, turps, and hot wash for hours.

Belt that was supplied with kit.

More next weekend.................
