Thank goodness for enthusiasts. A collective wealth of knowledge. And thank the internet for making it accessible

[@MartsGarage]

Cheers Matt. Thanks for watching.

Mart is a legend. What a fabulous neighbour to have. Wish he lived on my street. 😂.

[@MartsGarage]

Ha ha Hi Paul. Cheers for that. Remember the panel beating course we did? I've been trying to knock some dents out of my 32 sedan with varying degrees of success/disappointment. Thanks for watching and commenting.

[@robturner7945]

Galvanic corrosion strikes again! Great video 👍🏻

[@GP-pw5wb]

Mart, make sure you take the the water pump out from the middle of the "V" they increased the number of impellers to give a better water flow.

[@MartsGarage]

The pump was upgraded when the motor was previously rebuilt. Thanks for watching, GP.

[@jeffstercortan6724]

Very well done Mart.

I did a triumph v8 head job a couple of years ago. The left bank came off easy, but the right bank took me nearly two weeks to remove, using constant heating cycles and then dousing in wd40 and using a puller I fabricated to put constant pressure on the stud heads.the upshot being these engines are a nightmare to replace head gaskets even for the seasoned professional.

[@stevesalvage1089]

Check weather the heads have been pre skimmed , because if the heads are flat and un skimmed just clean them up , then you need standard thickness gaskets if you put extra thick gaskets you will find timing chains won't fit , unless they are stretched and worn , you can measure head from the head surface to the cam shaft hole , 4.427 in minimum, basically skim 20 thou use standard thickness , over 20 thou up to 40 thou use thick gasket , done this job many times , still interesting, cos they ain't bad engines, thanks for sharing

[@MartsGarage]

Thanks for the info Steve. The heads had been skimmed some time ago. Don't know by how much. As the engine was running with standard gaskets we elected to go with the same. That check dimension would have been useful but the motor is back together in real time. Thanks for watching.

[@Flordeh]

Always enjoyable Mart.

[@Fintoman]

I would recommend having the heads skimmed even if it means having to use the thick head gaskets on re-assembly. No telling if the head(s) are very slightly distorted after what the left one has been through getting it off. Nice new finish will really help make a perfect seal, too. I've been through this several times myself. Once you have the engine running, I can not stress enough the importance of retorqueing the heads after a couple of hundred miles and again at a similar interval. I think this was very often omitted on engine rebuilds and even from new. And was a major factor in head gaskets failing and overheating. I have always been religious about this on my engines and have never experienced any problems with head gasket failure. ARP sell bolt and stud sets for the TR7, you would need two sets for the Stag. The pt no is: 206-4208. They are more expensive but a much higher grade of steel than the originals. They recommend their fixings be tightened to 75ftlbs, a worthwhile additional 'squeeze' over the original 55ftlbs. It's only the grade of the bolt that limited the torque in the first place. Good job in getting the head off, welcome to the world of Stags, you're well on your way to be becoming an expert. 😂

[@MartsGarage]

Thanks for all the tips, Finto. We'll see how things go. Maybe a second head skim and thick gaskets might be needed further down the line.

[@bmwr807]

In the 1980's I had the same problem on my 1850cc Dolomite and used a similar method to get the head off. Unfortunately the stud had rusted into the block so I had no option but to drill it out and re-tap it the best I could. After having the head skimmed, the car lasted many more miles. A couple of years later, a local farmer called me as his Stag was very sick, running on 4 cylinders and overheating. I went out and found that only the drivers side cylinders were firing. Took the rocker cover off the left hand bank and the camshaft had broken above No 1 cylinder. I removed the head (thankfully all bolts / studs came out) and found that the head gasket had moved just enough to cover the oil feed to the camshaft. Had to fit a brand new head assembly but the farmer sold the the car straight away as he could no longer trust it!

[@mikef.1000]

Getting alloy heads off brit motors... reminds me of the time I nearly busted my boiler pulling the head off an XJ6 Jaguar. Ay caramba! Well done, and your persistence is exactly what is needed!

[@hogryder3366]

good job Mart, those water galleries look pretty grim too

[@MartsGarage]

Hi Hog. Yeah, I made a tool to clean them out as well as I could. Thanks for watching.

[@stumac869]

Impressed with your ingenuity in getting that head off. Had a Dolomite with the same problem and it took a day to get the ruddy thing off with tugging, pushing and wedges.

[@MartsGarage]

Hi Stu. Yeah, I imagine the advantage of the stag over the dolomite is having the other side of the block to push against. I can imagine what a struggle it was. Thanks for watching.

[@captainover-tighten6729]

You lucky lucky boy! Off to the village shop to get your lotto tickets! That’s a nice pneumatic recip saw you have. Thanks for posting

[@MartsGarage]

Yeah, that saw was a lucky find many years ago. I wish I'd thought of it when I did the first stud! Thanks for watching.

[@johnpeterson7245]

Well done , what an absolute bastard of a job. Many would have abandoned ship! Very good video.😊

[@MartsGarage]

Thanks John. Luckily I am a patient man. I have experience with decrepit Ford flathead V8s so am not put off by tricky jobs. Thanks for watching and commenting.

For what it’s worth I would love to see you continue with this project as I’m finding your work to be very interesting

[@MartsGarage]

Fear not, Bob, there's more to come. Thanks for watching.

[@kevinisaac9139]

Well done Mart enjoyed that came off easier than mine that bracket was a good idea 👍

[@karter5351]

Very clever. I had a Dolly Sprint with a same situation. I used load of techniques to get to the stud so that I could saw through it, but I never thorough of using a bottle jack

[@Steviegtr52]

That work place looks awefully close to the lovely Thunderbird eek. Well done getting it apart. Tip unless you already know. Forget wd40. Those studs could have benefitted from Plusgas. It eats away . The best stuff available. Helped me no end doing my vids on the Tvr. Steve.

[@martinfield1484]

Well done mart another excellent informative video

[@grahamsmith5768]

Luck was on your side to get them studs out of the block so easily. I've had to drill out and tap new threads on many occasions.

[@MartsGarage]

Cheers Graham. Yes, I guess 8 out of 10 successfully removed is pretty good going. Thanks for watching and commenting.

[@billburnhope2176]

So much more to do!

[@graemeburr6463]

Good one Mart always a bit scary when doing a mates car . We recently cut an old safe loose that was bolted to the floor that we couldn't get into to unbolt. Once we could move it up a bit we got a hacksaw blade wrapped masking tape around one end to make a handle and cut it loose......a prick of a job!

[@NotMarkKnopfler]

The stag is beautiful. I hope the owner decides to get it back on the road. I wonder if he would consider a Rover engine conversion? They seem to be less trouble.

[@MrBrendog67rat]

Wow Mart! i think you dodged a bullet! what a job, but i think the Crusty Flatty was worse! you will get it to run, i think you like a good chalenge Brendan

[@peterknight4692]

Nice job!. That larger stud hole looks like it may have had a stuck stud before and it ended up being drilled out.

[@MartsGarage]

Hi Peter. yes, I was thinking much the same. Some sort of butchery went on, that's for sure. Thanks for watching.

[@mikewilson631]

It coming along Nicely there Mart some stuck bolts and snapped studs that press let go with some pressure . Heavy old brute of a v8 big cast lump

OK too late now but did you put penetrating oil or heat to remove those studs ? obviously the type different types of metal caused the corrosion.

[@paulmuff9883]

Well done 👍

[@austinswallow]

what a 'mare, still, you got there in the end! Well done! Did I notice a lapse in the eye protection whilst using the angle grinder? I have prescription eye googles and these wrap around the eyes totally give full protection. Thanks for sharing.

[@MartsGarage]

Thanks Austin. Yeah, my bad. Something better than a pair of glasses is always preferable. Thanks for watching.

[@julianannells3245]

Just a note. When back together, unusually the ign is timed up on number 2 cylinders

[@MartsGarage]

Yeah, that's a bit non conventional. Luckily I found a factory repair manual on line and that was a great deal of help. Thanks for watching and commenting.

[@markrobinson8539]

I wonder if the damage to the bad stud hole was caused by the use of a spark eroder to get the seized stud out in the past.

[@MartsGarage]

Dunno, Mark. Some sort of heavy handed butchery I would suspect.

[@larsbr4519]

My Father had a Saab 99 with the four cylinder Triumph Engine. It Overheated so we changed the head gasket, and we had to saw of two stuck studs with a loose saw blade. NOT FUN...

[@MartsGarage]

Yeah, Lars, I remember the Saabs using the Triumph motor.

[@sw5carbon]

good afternoon where can i get a plate like yours

[@MartsGarage]

Dunno. Mine was a lucky swap meet find. Try ebay or facebook marketplace or whatever is relevant to your location. Search for surface plate. Thanks for watching.

[@billweston6579]

They used the same engine in the SAAB 99 1.85L with only 1 bank of cylinders. It was a terrible design. You can’t push the head off with a Jack. We had the front wheels off the ground using an engine crane pulling on the head. Later 2.0L motors did away with the angled studs and had straight head bolts and a wider rocker cover.

[@MartsGarage]

Yes, I knew someone with a Saab that had that engine. I remember him trying a screwdriver in the stud slots wondering if they were some sort of adjustment. Funny what lodges in the memory banks. Thanks for watching.

[@fredjones1238]

to bad you didn't have a Sawzall but u got it well done . would be great if you do all the work and get her up and running

[@MartsGarage]

Yeah, the tool I used on the second stud was the grandad of the sawzall. It was easier than doing the first one by hand! Thanks for watching.

[@BrianPaterson-f3i]

Mart wins !

[@MartsGarage]

Ha ha cheers Brian. Thanks for watching.

[@lrcb40]

Mart: get some of them fancy front wing heavy duty covers to protect the car and you’d have somewhere to rest the head once freed up! 🙄

[@MartsGarage]

Yeah, after watching the first video and seeing how exposed the wings were, I did cover them up later on.

[@jacquikowalewsky7691]

Most interesting, looks like some serious corrosion been going on there. A good clean and good anti corrosion antifreeze for the rebuild eh?

[@MartsGarage]

Yeah, we elected to go with the blue stuff. Don't like the red stuff. The cooling system tends too get closely monitored on the Stags due to historical issues.

[@harleyveejay]

That engine design is very strange and looks to be miserable to work on. Great job on overcoming huge obstacles. In the first video you gave a history of that engine and I'll have to go back and watch it to recover the info about it's evolution.

[@lrcb40]

Strange? Compared to?

[@dustym9610]

Poor design I would think looking how the engine slants down towards the bulkhead and that's where most of the corrosion shows itself but really enjoying the channel
