Right ive done a bit more today and over the weekend although nothing too exciting.
I found an Aqueous heated parts washer at work so raped that and cleaned a lot of my engine parts in it.Including a spare cylinder head i had.I stripped the valves out and decided it was in better looking condition than the one ive just had skimmed so im going with this one now.
1st off ive had my engine block on the bench and set about the fantastic task of gapping piston rings.
This entailed fitting the piston ring in the bore to 15mm from the bottom and measuring the gap with a feeler gauge.0.25-0.45 is what were aiming for so i got them all to about 0.35.
Fecking tedious job!
Then i pressed all the small end conrod bushes out and checked the thing was in tolerance which it was.I also got the mrs digital scales out and started balancing the rods.I managed to get them withing 0.5grams of one another so that will do me.
I dont have a pic of this but i then polished the rods and then pressed the new bushes in.The problem with the new bushes is they dont come with an oil hole,you have to drill it and ream it yourself.
I can go and buy a 20mm hand reamer and drill the oil hole myself and then clean the burrs out with guitar wire but i think i would like to get a machine shop to do it for piece of mind so i will get them dropped off this week sometime.
Once i had stripped the valves out of my new head and hot tanked it again i decided to give it all a good clean up in the ports and set about porting and polishing it.
Now i know this is going to take hours and hours and hours and ive got to be careful not to screw the valve seats(guides dont matter) so i had a few hours de carbonizing the valve bowls and the inlet tracts,smoothing out any steps and casting marks etc.
I then hit it with the catridge rolls to see how it looked and it is coming on well.However it is FAR from done.
Oh i got my front cross member enamelled as well as my drive shafts.
This also came in the post today so i can set about checking my oil clearances on all bearings now
Tomorrow im helping a guy off vr6oc swap an engine so i wont get back on this while thursday but im hoping to get some more done then
In other news a very good detailer in my area
http://www.deep-shine.co.uk/ is sponsering Hulloween Cruise
https://www.facebook.com/events/413393745380201/ and has a stand there for 2 cars and has asked Potter to take one of them.So im going to book a rare saturday off work and go through for that.
Im also debating what valve springs and valves to go for.Im considering going with Shrick valves,keepers,shims and followers and using Ferrea sodium filled valves but im still researching atm so that might not be for the next month or so.
Thats it for now
