Red Turbo Esprit recommission project

[Chillidoggy]

Do you have to heat the cylinder head to push the guides in/out?

[Guest gbowick]

No, but you do need a stepped drift of the correct dimensions to avoid damaging the guides during installation.

[Chillidoggy]

Presumably it's a different process to the later heads in that case.

Be interested to learn what the cause of the pressure loss is, Wayne.

Got them out with a drift and heat. Real b#%<~*d 

having the head skimmed and new guides and seats recut. 

Think heat might be required to get the new in.

Just looked in the service notes Wayne. Not sure which one yours is, but the '93 onwards cylinder head should be heated to between 100 - 150C before removing/installing valve guides. Top tip - Best to wait till the wife is out before sticking cylinder head in the oven, I've heard they can get a bit niggly about that kind of thing.

My pals workshop had the calor gas heater fans running while I was there so I stood the head in front of it. I was blazing hot and I had to wear leather palm gloves to do the job. I can’t see how they would come out without heat to be fair. And the reverse is the same. 

Gosnays is the workshop where I’m going to get the work done as I don’t have access to a spare machine any time soon. 

Confidence is high....✌️

Gosnays? They still in business? I used them about 40 years ago for some engine work, but thought they'd gone under. They should have an oven for heating the heat for valve guides, in that case. Let us know how you get on?

Those photos should be on the top shelf, under a plain cover.

 

Good service? How long did it take them?

[top-plumber]

Polishing the head before installing the valves in the new guides. Helicoiled the 8mm bolt holes all over. Nearly ready to replace valves and grind.

I did all the polishing and helicoiled the holes. 

They replaced the guides recut the seats and skimmed the head and faced a flywheel in 2days. Must have been quiet after Christmas ✌️

I reckon so.

Well done Wayne   That is a proper bargain imo 

[top-plumber]

Engine out of the red Turbo again. Doing a rebuild of the bottom end and new rings with head rebuild also. 

Should have done it in the first place really. Oh well live and learn 

[silverfrost]

Good luck with the rebuild Wayne,   

Yes it is east to say you should of done it during the resto,  but it could of gone on for plenty more miles,  just murphys law.   Anyway another project on the car now to keep you busy,  keep the pics and updates coming. 

[Chillidoggy]

I feel your pain.

[top-plumber]

The crank is out and needs the mains ground but the ends are good as I have measured and checked roundness. Pistons are good and rings were all in one piece. The oil rings were very sticky so may have been allowing let by. I have honed the liners and am happy with the finish. New rings ought to be the only requirement now. 

The head is in good condition won’t need machining. I will just check the guides on this one and clean and re grind. The spigot bearing will be changed. Not going to do the upgrade on this one as it is ok as it is. Only a small amount of push back of the bearing. New spacer and bearing will be fine. Cleaning and waiting for parts now.

The red Turbo had a broken lug where the cam carrier bolts down. Drilled it out and had it welded. Dressed the area and tapped out ready to accept new 8mm helicoil.

[Sparky]

Lovely stuff.  May need to do much the same shortly...

[top-plumber]

Also the head is now sitting on the block of the white Turbo. Slowly but surely getting there

Cheers sparky, only £42.00 to weld at gosnays. Dressed it by hand with files in the garage. Hope I got it flat enough. Reasonably confident. ?

Gawjus!
