getting ready to fit the upgraded head with upgraded valves and camshafts. heres whats been happening.

 

right here we go!

 

had a busy day the sun shone and i started again, got loads done before i really made a big mistake!.

 

undoing a really stiff bolt , my hand covered in grease slipped off the ratchet and i hit my bad finger into the car with a massive force, then a big crack! seems my joint popped so now its back in the splints again with bruised tandons.

 

as you can see i got a lot done but nothing conclusive.

 

i also got so far and basically chickened out of doing any more a: due to the finger and b: because im a coward.

 

pics follow

 

notice the lovely extra throttle spring attatched a bit stretched just because they couldnt re-attatch the one that was there, all done now though and removed that one.

also notice the lovely crap in the coolant inlets behind the carbs, i dont think this thing was ever flushed.

progress today was slow and tedious, not helped by this damn finger!!

 

i removed the fuel line feeds to the regulator top and bottom, this way the regulator could stay attached to the carb side box ( i don't know the tech term for it sorry!) on the side next to the firewall was a small black tube connected by a nut to the side of the box i removed that. I then proceeded to remove the other coolant rail from the top of the carbs.

 

The nuts on the carb mount studs are M14 size, mine were actually easy to take off and only one stud undid in the process, a quick blast of wd40 while off and grips on the stud i was able to take the nut off the stud, clean it up and re thread it into the head. I have now cleaned all the studs up and given them a coat of wd40, until i coat them with some copper grease and new nuts.

 

Taking the carbs off was not easy at all, the whole thing would not budge for ages, i did think about just giving it a good tug but after (yep you guessed it) slamming my finger into the side of the carb housings i thought better of it. Instead i just gently pulled on the side closest to the rear of the car first and got a lift there, i then put a screwdriver under and gently prised the end up the rest followed and i was able to lift the whole thing off.

while off i had a quick check to see how much crap was covering them before they go off for refurbishment and ultrasonic cleaning. (more details on this process and details of the company doing the work to follow)

As you can see one half came up very nicely and I'm sure that when returned to me they will look fantastic, before refitting.

I also drained the oil from the cam towers with my Clarke oil syringe, and emptied it into an old Pepsi bottle i had laying around.

 

Also much to my surprise i found that one of the main bolts and nuts that hold the engine to the gearbox was missing, i have yet to check if any others are missing. As i have contacted the last service agent twice and spoken to them twice and never been called back by them twice it is not difficult to understand the level of incompetency of the work carried out on this cars last "c" service.

I am now ready to take the cam towers off, i couldn't find a torx E10 socket locally so i will order one Monday, as the cam towers are held on by these special bolts

 

 

The plan is to at least get the engine bay to an almost concourse level of cleanliness with the boot panels all colour coded and the carpet sections replaced with carbon fibre matting.

 

ok its not a zed but i thought you might be interested!!

part two:

 

the engineer fitted brand new and upgraded exhaust valve guides made of bronze, what he pointed out to me is that inside they have a series of small indentations these collect and retain oil.

here is the head!!! with the new guides pressed in, fantastic job!

 

DSCN3850.jpg

 

here is the base of the head it will be machined this week

 

DSCN3851.jpg

 

here is a close up of the valve seats all newly machined.

 

DSCN3852.jpg

 

here are two pictures of the valves all cleaned up and machined

ok heres the news then.

 

none of the valves were damaged, all the valve guides for the exhaust outlet were shot, the head is in very very good condition, he is replacing the cam seals next week and also doing the tappets and shims.

 

he was surprised that the valves were in such good condition.

 

so its looking like i will be getting the lot back within the next week or so, all i have to do now is get all my bits in, replace all the pipes and clamps and remember where everything goes!!!

 

then its over to someone to time it all up for me and re-fit the belts etc.

 

so all in all good news so far reguarding the head assy.

this was done in two parts as the thread has a limit to the amount of picture links in one post
