So I bought myself a V12 engine out of some 1976 Jag. They guy had it laying around and finally decided to sell it. He said it was in running condition 3 years ago when he took it out of his car. So I bought it and brought it to my garage and started to take it apart. Here are some pictures, sorry the bad quality I was using a phone with bad lighting.

The day I got it:




After taking out all the wires and the intake manifolds and pin needles and an ants nest this is what it looked like.







Then couple of days later I took off the cam covers and this is what I saw.









After several more hours of trying to get other parts off this is what I saw and how its sitting now.













So next im trying to take the heads off but they wont budge..any ideas of what I should do? I think I took all of the bolts off. I also cant get the bolts off under the exhaust manifolds because of the rust. What are your guys thoughts on my project?

 

Sorry to say this, but that engine is toast. You'll spend more time attempting to salvage parts than is viable - much easier to buy another engine that runs.

I've seen some grotty engines in my time but that's another level, and sad to see.

 

Yea thats sorta what I was thinking too. But I want to tear it down to the bare block just to see what Ill have to go thro if I decide to rebuild another engine. This engine still has some good parts that Im planning on cleaning up and maybe putting up for sale to atleast get some of my money back.

 

Wow.....I'm absolutely no expert, but that is bad bad bad my friend I'm sorry to say.

Hopefully you didn't pay too much for it and can get yourself another one and move forward.

 

Shine her up, and you've got a great coffee table candidate! No sarcasm.

 

Haha thats funny that you say that...thats the same idea I had after I took the first cam cover off. Thats another reason why I want to finish taking it apart, if the block is in good enough shape Ill have a new coffee table

 

What happened to this motor? I can bet you comrade that it was submerged for a couple of years.
BTW, heads are super hard to pull even on a perfect motor, so even the coffee table idea is not an easy one.

 

I agree with the other posters here...

The head and block castings are most likely corroded internally beyond all use. If that is the case sell the block and heads to a metals recycler for their aluminum value. The rest of the parts go in the trash.

 

im still waiting on a a headpuller just so i can make my coffee table.

 

Yea thats my back up plan. There are still some good parts from this engine. The intake manifolds are in good shape and the exhaust manifolds are not bad either. Everything else is trash.

 

Does anyone have a cad drawing or measurements for the headpuller? I want to make my own.

 

Considering you aren't going to be able to salvage it and only want to keep it as a potential coffee table, you might try this: Block off all the coolant ports and fill it with CRX or some type of calcium/rust dissolver. Let it sit for several days, then try pulling it apart. It should remove/dissolve most of the corrosion on the head studs and you may be able to pull the heads off.

 

You have certainly picked a challenge for your first engine rebuild. I think it is safe to say this project will end as a partial strip down and go no further!

 

i agree. this motor is corroded beyond all repair. the fact that its a V12 has nothing to do with the problems youre looking at as far as a rebuild is concerned.

cams, cam journels, valve seats, everything is totally ruined.

 

It doesn't look like it is suitable as a boat anchor, it looks like it has already seen such service

 

Download Kirby Palm's "Experience in a book" along with tons of good info there is a drawing to make your own head puller.

 

ive got a crap ton of HE V12 parts btw. carburetors, cams, heads, pistons, rods, crank, etc.

 

IMHO
FYI: I owned a 77 for 20 years and an 87 five years. Purpose built an S as GT1 race car and raced it 8 years in SCCA https://www.facebook.com/jon.frey.568?fref=ts
Here's an opinion from all the wonderful experiences I enjoyed with the V-12 lol.
Do not rebuild a 12
Buy a rebuilt 6 or convert to a Chevy small block 350.
The conversion takes some effort but is a very acceptable alternative
Radiator, springs and shocks, engine mounts, same 331 rearend. We went to a T11 four speed and tilton hydraulic clutch.
John's Cars in Dallas my still sell the kits for the conversion.

 

What is INCLUDED in a John’s Cars conversion kit?
The JCI "Regular Kit" is the most complete kit available and contains well over 100 pieces including:
Front isolators (engine rubber mounts) and mounting brackets (patent pending) with hardware
Transmission mount and crossmember
Shift linkages
Engine function wiring harness – custom made, 100% "plug-in" and color coded to your Jaguar
Power steering pressure and return hoses
A/C hoses – custom made with crimped collars (no hose clamps to cut yourself on), Schrader fittings (charging ports) where you can get to them, and barrier hose (compatible with Freon 12 and R134A)
Radiator filler neck, cap, heater hoses and fittings
Accelerator linkage
Oil and temperature fittings/senders
Speedometer hookup and calibration
Miscellaneous hoses, clamps, adapters, spacers, hardware, etc.... EVERYTHING!
Illustrated, step by step INSTRUCTIONS

 

jon the OP dont have the car, only the engine!
