But there are many competent people both here on this forum and in real life that can do it.

And I'm sure it was said more than 1000 times that the world was flat, but guess what they were wrong too.

You said it best "Not one has ever been brought back for any major problem" Like I said you can not rebuild an engine at home. I bet your engines did not last more then a few weeks or months with-out leaking or burning oil or this and that going wrong. So why did you rebuild 50 engines or was it you rebuilt the same 2 engines over and over again

Rolm, have you ever heard of machine shops?

All it takes is a mic set, some feeler guages, a good rebuild kit, a machine shop to do the machining, and some brains to rebuild a motor....in your garage

You have to have a little brain power going for you to able to rebuild at home, not alot but enough to able to read a book and use measuring tools I can see how someone would think it is not possilble to do at home lacking these skills.

Rolm,

You are so full of &%^&*%^&^* it's pit-a-full. As a matter of fact all of the engines but one are still running. The one that isn't is because the car was wrecked. And not one of the engines was rebuilt more than once, nor did they leak oil as you suggested. You are just a blowhard troll. You wanted to get under my skin some, and I'll admit you did but not quite the way you wanted to. All this shows is what an idiot you really are.

When you grow up, then we'll let you play with the big boys. Until then you'll have to stay in the toddler playground.

Regards,
Heli

Blue puff of smoke when you tap the gas (can't remember if this is rings or seals). Also, when I pull the valve covers, I noticed that several seals had moved up the stems and were no longer sitting on the valve guides. These are the Crane seals that came in the kit for the hyd-roller cam. However, it seems to be puffing out both sides intermittently and the seals on the driver's side look fine. Intake gasket has been replaced and reinstalled using that nasty red Permatex goop (for lack of a better term) around the intake ports.

This is starting to bug me since it was using a 1/2 quart every 3000 miles before. Any suggestions / ideas would be appreciated. Any idea on how much it would cost to replace the seals (I know it can be done with the heads on).



PS. Car goes to body shop this week so any solution will have to wait.
Steve,
I hope you used Permatex "High Tack" rather than Permatex RTV "gasket in a tube" silicone. The silicone RTV is not good to use around intake ports as the gasoline will disolve it. Intake gasket leaks can cause high oil consumption and are more common than you would imagine.

The Crane teflon valve seals require that the valve guide boss be cut down to the proper diameter to accept the seal. You can not just slap them on there. They can come off even if the head has been properly machined as yours did so I do not like them in general. They also may have been hammered if the cam lift is too high and the underside of the retainer may have hit the top of the seal. Been there, done that once too. You can take them off and inspect them for that. Check the clearance at assembly.

Just a few things that come to mind.

-Mark.

Mark,
Thats the stuff, Permatex High Tack. Love trying to clean it up. Guide was cut down by the machine shop. Cam lift should be OK (.488/.509). I am going to live with it till the winter and then I'll probably swap the Crane seals for a new set of the Edelbrock ones. As I understand it, it is a preety simple swap if you bring each piston to TDC in turn and use a compressed air source to hold the valves up.

Steve,
I do not like the compressed air method myself. If the valve comes off the seat for any reason, it might drop in.

I use the "clothesline in the sparkplug hole" method. You feed in a length of clothesline and bring the piston up to the top while you change that cylinder's seals then repeat for the other cylinders. A little more fool-proof and does not require an air compressor.

-Mark.

Default Deja vu on Rebuilds

I have a 73-454 with the same illiness. However, it was built by an engine shop. Story goes as follows. Had the heads reworked, new valves, new seats, new PC seals, new springs etc. All new.

Had the short block built at a "pro shop" Got the pieces together and damn if did not smoke right away. Took it back to the "pro shop" and they pulled the entire engine, disassembled totally, mic'ed all parts, put different rings in, used a different intake gasket type and said they see nothing that will cause oil burning or puffing.

Ran the car for about 300 miles and the damn thing started puffing blue when you got on it or reved it hard.

This makes one rethink how much I like this hobby - ready to take on building bird houses.

All suggestions are welcome.

PS - even having it built is no guarantee.
