Hi all
Bit more done today, new plate just about finished.

Just the threat of that plate should do the trick. It's amazing the amount of friction some gum can produce.

I saw something today with an old seized engine and they used coca cola to free it up...

Hi Kevin
I have heard of using coke to clean tarnished metal and I had some success with vinegar to clean up a stripped thread on a thermostat housing so if you could submerse the engine in coke it would definitely get rid of some of the corrosion.

Hi all
Definite progress today as we have a nice gap between the head and the block all the way around and the corner that was stuck has lifted. The new plate has not deformed like the other one but it has bent some of the rocker mount studs. The good news the 8mm bolts screwed down on the exhaust side tighten up now and don't just bend the plate. This means the plate will be left under tension overnight and now it is nearly parallel with the block I am confident it will surrender soon.

10/10 for perseverance, and a well deserved result seems around the corner

Superb!

Very interested to see photos of your studs and the holes in the head when it does come off. Would like to see how it compares to mine.

No further damage to the rocker saddle studs?

Hi Dave
I'm afraid I got carried away and failed to notice the rocker mount studs had been bent but no more stripping...I will investigate today. I think some physical fastening of the plate that seems unbendable to the exhaust manifold studs is needed to keep the plate horizontal and pull evenly. It might be worth (if I was doing this every day) to get the plate cut with tags on that side and get the steel supplier to bend it at 90 degrees and drill the holes for the exhaust manifold studs.

Hi all
More progress today but still not lift off. With the use of plastic wedges and a 2lb club hammer via some sturdy timber we have edged the head further up off the very corroded studs. I only had a couple of hours of playtime today so I left the head to soak with WD40 and engine oil. Very satisfied with the progress as the head is pretty square to the block and with judicious tightening of the plate bolts and a few love taps with the club hammer via a piece of 4 x 2 timber has moved it up about 5-6mm. The only studs not taking oil down are the exhaust side ones just like the other head but now I can access them from below I trust to WD40 and the oil. The rocker mount studs have been in a bit of a battle and will need a make over with a die or replaced from the spare head also a couple of rocker cover studs have took a hit.

Have you tried the 50/50 mix of ATF and cellulose thinners? It significantly out performed anything commercially available, including WD40, in a magazine test some years ago and I find it very effective.

Heat did the trick on my recent stubborn stud, perhaps softened what turned out to be to congealed gum as much as corrosion. Won't be long now.

Hi all.
I put some of the mixture you mentioned Frank down the tops of all the studs but the exhaust side ones have not pulled any lubricant down till now. Had a couple of hours tinkering yesterday and was very pleased with the progress. I removed the plate to look at the rocker mount threads and they were fine but clogged up with the obviously weaker steel of the nuts I had used so I cleaned them up and replaced the plate using the original nuts but without the big spacer nuts. This meant the plate would drop closer to the head and be more secure as we got the nuts well down the stud (see pics) The screwing in of the bolts produced a nice gap and it was even all round the block and the next issue will be the tops of the head studs will disappear inside the head. I am thinking of using a short length of 10mm rod to push down on the studs under the 8mm bolts through the plate so as not to damage the head. It feels as if the head is going to fight all the way against the plate and bolts so a couple of days will probably see it done.

Hi all
Had a slow and frustrating day yesterday as the head has moved up nicely but has stuck on the front right corner again, at least you can see into the bores now and it looks reasonable in there.

Sorry about the upside down picture ?

For next time.. it could work getting some brake line, cut some teeth into it and drill out the dirt around the studs. https://youtu.be/Zu5JLv0GErM?si=6JZ_bXR_Mu5_ud5u see 22.00
