last clean up needed to fit heads, I like to use a nylon wheel to really get the aluminium oxide off, I think this is what causes seal failure.

quick check of the gallery plug that I forgot to do before...looks fine

dry moly on studs

green orings on

sealant in gasket, this is where VR is easier than Dirko because you get a nozzle

I'm using AF again, paintbrush gets a very thin even layer, this is a coarse bristle brush, fine can shed hairs you can't see

ImageP1100311 by Paul_Barr, on Flickr

rings in and do the other side

ImageP1100312 by Paul_Barr, on Flickr

sealant on other side of water jacket seal

ImageP1100314 by Paul_Barr, on Flickr

ImageP1100316 by Paul_Barr, on Flickr

25Nm with dry nuts and leave for 30 mins to allow the Hymolar AF to creep out of the joint, just enough time to post this.....

I recommend using Hylomar on the fire rings, it is a non-hardening elastomer specifically designed for this type of high-temperature sealing requirement with differential rates of expansion between elements (Rolls Royce developed it for their large jet engines). It must be used according to instructions, applying it to one part, smearing that part against its mate to create a film on both parts, then the parts separated and the volatile vehicle allowed to gas off for a few minutes. Then the parts are assembled and brought to 1/2 to 3/4 of full torque, then wait 20-30 minutes for the elastomer to "creep" under pressure, and finally bringing the fasteners to full torque. This means both sides of the fire rings must be coated and smeared to the heads and cylinder tops. The head capnuts can be first assembled dry, then after all have been brought to final torque, taken off one by one and retorqued with sealant. Hylomar can also be used under the capnuts, which will allow retorquing if ever necessary without the need to drain coolant, remove the nuts and apply new sealant, since the Hylomar never hardens. There are several variants of Hylomar, get the Advanced Formula ("Hylomar AF") for its superior workability, or the Universal Blue spray if you are willing to mask your parts carefully . There is a special solvent available as well, "184", which makes clean-up easy, although I believe acetone can also be used. Hylomar products are easily found on eBay or Amazon.

30 mins have passed so took nuts off one at a time and added yellow sealant and retorquesd each one to 25Nm

Marco Mansi Uses Dirko and Tencentlife suggests Hymolar but I have no real reason to try anything different.



ImageP1100318 by Paul_Barr, on Flickr

then finished the torque to 40 then 50Nm
always makes me nervous going to 50Nm
other side will have to wait until tomorrow

Other head on today

ImageP1100320 by Paul_Barr, on Flickr

ImageP1100321 by Paul_Barr, on Flickr

ImageP1100322 by Paul_Barr, on Flickr

oil seal hammered in

ImageP1100323 by Paul_Barr, on Flickr

oil pressure relief valve in with new spring

ImageP1100324 by Paul_Barr, on Flickr

tighened with a pieve of sheel metal and a spanner, I wish there was a tool for this.

ImageP1100325 by Paul_Barr, on Flickr

late exhaust support brackets on

ImageP1100327 by Paul_Barr, on Flickr

stainless drain screws fitted with new copper washers, these didn't come with the VR kit which is disapointing, no oil filler pipe gasket either. Luckily I had some from an old elring kit.

ImageP1100328 by Paul_Barr, on Flickr

I have assembled and fitted the push rod tubes with rocker covers just to keep dirt out, they will need to come off again when tappets go in.

Something very therapeutic reading this thread...................

..................... Try searching for a drag link socket. I picked one up a while back to nip mine up a little as was weeping.

Mine was a bit of a random find on ebay, can't remember the exact search terms I used. About £4-5 delivered.

That looks a better fit than the one I picked up - Its a nice feeling having a tool for the job, even if it is only used once in a blue moon.
