Glad it was an easy fix!

I let a blown head gasket on a Previa supercharged van sit for years and had a similar issue. I rebuilt and ported the head and valves. The block deck was pitted severely. I did not dissemble the block. Left it in the car. I cleaned the rust out with a red scuff pad. Then hand sanded the cross hatches back in with 600 grit wet and dry. Cleaned out a zillion times with oil and paper towels. Glued the head gasket back on with JB weld in the pits. Surfaced the head .020”it is running to this day 20k Miles and 4 years later. It currently has a custom stainless mandrill bent 2.5” exhaust with long tube try Y header I built for it. Boost with stock pulley is now 2 lbs. was 6lbs. Before mods. I had to install a high flow fuel pump to maintain fuel pressure at full throttle. It has a massive power increase and 4mpg mileage improvement. Does not burn oil or smoke. No piston rattle and 178k miles and going strong. Next up is bigger injectors, matched to Supra airflow meter and custom crank pulley that a made for more boost. Then Supra intercooler. ( free parts I had laying around. So cleaning off rust worked for me.

It will definetly suit to my goals of tuning/racing where my channel is all about I have an Cadillac Seville Elegante from 1980with the 368 block in it now since i need and want more HP this would be perfect, so yeah But nothing too lose, lets continue

This is a great idea, I am just getting into the Cadillac stuff and would love to see more on this engine. If you're going to put it up for a subscriber then I would volunteer, I have a 68 C-10 long bed that needs an engine and transmission to run.

So wanted to see you fix the heads with some fire rings and studs and see this thing make 1000ft-lbs with the turbos.

Great video keep it up Richard . Gm ls lt FTW

LOVE EH. he has i t going on. great honest source of NO BS knowledge.

You threw boost at a 8.1 liter Caddy? LMAO.. That is awesome.

Quick check your distributor. Pop the cap and put a socket on the crank. Wiggle the distributor shaft to feel any play. Move the crank back and forth to make sure the cam and distributor gear are not binding preventing you from feeling the play. Next, grab the advancement weight and pull out ward. You may need to pop the weight spring off for this test. There should be no in or outward movement only left and right circular movement on the pin. Bad weight pins will give you vary early timing advancement, over advancement and erratic timing at idle.

I'm building my 472 (1st build) - please keep testing🙏 Will be seeing Cadillac Co. Later this year👈

I just bought a low mileage '75 Deville 500 engine for my '93 C3500 crew cab long bed truck. YOUR 500 really NEEDS to be in my 2009 Crown Victoria Police Interceptor!!! It's all black and already such a fun car to drive. I already have a name for it... The Coupe DeVic!

A New stroker kit!!! 😄😁😆

Love the auction off idea. I got a few cars a turbo Cadillac motor would be super cool in.

What I learned is if you’re going to delay pulling the heads on a blown head gasket you should probably drain the radiator and run it without coolant to make sure the cylinders are dry 👌

I love the 472/500. I have a 73' 500" engine sitting in the stand for years with a big turbo laying on top. If I had enough time to rebuild it, it gonna take place in my 62' Cadillac and drive the shirt off from the Volvo turbo guys, haha.

Richard, the Cadillac is a very durable engine. Better head gaskets and or head studs would correct that problem. Mainly the head gaskets. The Felpro doesn't have the 'good' fire ring. It will hold up to pretty high cylinder pressures provided the ignition timing is in the right range. But too much timing along with detonation will kill the gaskets quick. Normally at the rear of the block above cyls 7 or 8. They're closest to the water passages. Ball hone the cyls with WD40 and call it good. It'll seal up. I've really enjoyed your series on the 500 Cadillac.

Fire rings and head studs. Send it. 🤘😎

You know this man is pretty good at what he does...I want to see him turbo the Camaro 3.6 LFX v6 engine bet he could take it to new feats👀

Dingle-ball hone + studs for the win!

That would be quite a drive to pick up a motor!

That is odd that the head gasket was pushed into the cylinder instead of out into a water jacket. This would be a great engine for an old Suburban!

Ball hone and boost

I would bet that it was too much cylinder pressure... lifted the head. Those head gaskets are so weak. Head studs MLS put it back together... with ring Gap and put it back on the dyno. Add a degree or two of timing and close the wastegate... to the top.

I had an Acquaintance about 1995 that had a NOVALLAC ( 72 I think?and 500Caddy with 472 heads) it was a Fast Clapper, about 7.50s 1/ 8 mile, I remember he only had about 2500$ in the whole deal! It's was a Torque Monster.👍👍

Forgot to mention stock supercharger is two lobe roots. Electric clutch with decent inter cooler. But system has no map sensor. Uses tps and airflow meter to calculate load and switch bypass valve and supercharger charger on. Ecu also operates AT trans. First pass trans slipped going into second. I changed out fluid to Redline racing and raided line pressure. Spins tires in first and second now once super low stall speed is overcome. Hilarious passing “sports” cars in faded paint beat up van.

Pretty sure I would be the only one with a 500 Caddy in a Squarebody in the UK (I'll even pay the shipping). :-)

Richard, I am glad it was just head gaskets. I hope the old Caddy finds a good fun home where it can spend its golden years spinning tires and scaring girls. Long live King Caddy.

Like you said, its just a head gasket. I know some honda guys like like to wire ring their decks with positive set sleeves. Insane overkill on getting the head to seal. What ends up happening is the head can't lift and it hurts something else. If you have a racecar and a spare engine in the trailer that's one thing but for most normal guys the gaskets can act like a fuse to stop you from eating the important stuff.

@@Future-Preps35 I like copper head gaskets but they are kind of specialized now. With how good mls gaskets are now guys that build race engines won't use copper unless there is a weak head bolt pattern or lots of power. For this Cadillac engine with its stock pistons I really think that copper gaskets are serious overkill, if you are lifting the head you are doing something that will hurt something that is harder to fix.

You may try evaporust on the cylinders. It is a rust removal soak that works really well in my experience.

Comment for the algorithm 👍

Bet if you'd ran it boosted with the caddy shop heads to a higher rpm you'd not have blown the head gaskets. That's a ton of cylinder pressure at a low rpm. Get the aluminum heads back, stud it and put some real boost in it

Seems a bit odd the the second cylinder back on each side suffered from head gasket failure. And the failure was on the intake manifold side of both gaskets.

I’ve been sitting on a 500 caddy for 15 years waiting for that day... it’s going in a 84 Chevy one ton with 34,000 miles that I’m doing a “retro Silverado “ with the 2020 grill/headlight assembly with Denali running lights updated mirrors, 65 phantom Cadillac taillights etc. with 11/2 ton Volvo C303 portal axles and a V-plow themed “yard truck” I’m a humble man but if that ole beauty needs a good home with tough love I’d be forever grateful 😁🤞

Man I would absolutely accept that 500 and put it in my van - and the 454 I'm currently building I would give to someone else...!

Soak the bad cylinders in diesel and atf for a week. Vacuum all the crap out of it and slap it back together without copper coat. It will run perfect. That's a mens warehouse guarantee.

If that cyl can't be saved ( and as long as the piston don't get damaged removing it ) it would be cheaper to sleeve that one cyl back to match the piston that's in it rather then bore and hone all eight plus new pistons plus matching the new pistons weight to the old set being replaced.
