L67 rebuild ... sort of......NO 56K!

[1fatcat]

I am rebuilding an L67 and thought you guys might like to see the project. It is not a full blown rebuild, but pretty much all the same steps will be taken...just not all the same parts replaced as a full blown rebuild would be. Please be patient, I will try to finish this fast, but expect some delays.

Just picked up the engine block and heads from the machine shop today, I had them cook the block and heads just to get them a little cleaner to work with. They will still need a final washing.



After cooking.



Head bolt holes before cleaning/thread chasing


Durring thread cleaning


After thread cleaning


New cam bearings installed (by machine shop cuz the tool is $250)


Light shining through one of the oil gallery holes, use a gun cleaning kit to scrub these holes before final rinse/cleaning.
Front of block prepped
deck prepped

That is all for tonight. I need some beauty sleep...badly!!!

is this going in your bonnie ?

[01bonneSC]

You boring out at all?

[1fatcat]

This engine is going into a fiero. Not boring it, just stock bore and honed for new rings.

well than...my statement from the other thread still remains about your bonnie..

[1fatcat]

Block cleaned w/final rinse. Checking bearing clearance

Crank in place. Remember, no oil should be used when checking bearing clearance. And don't rotate the crank either.

Checking crank end play

Crank end play can be checked on the thrust bearing too with a feeler gauge

Plastigage compressed


Torquing mains to 30ft lbs

And now an additional 110* rotation

Main cap side bolts, use a sealer here to keep oil in

And torque to spec. 11 ft lbs and 45* rotation

Rod bearings are getting replaced

Measuring piston clearance

New rod bearings installed

Installing pistons

Measuring rod bearing clearance with plastigage


Lube up the bearings with assembly lube

Cover the engine when your done for the night

So thats it for tonight, just got the crank and one piston it, oh, and the cam. I don't get much spare time for my projects. :(

Looks like fun!!

That measuring is critically important, but takes forever....

[harofreak00]

Loving the pics, keep it up

[00Beast]

Oh, and BTW, what cam are you running?

[1fatcat]

Just the stock cam. I didn't want the added strain on the valve train or the extra expense of upgrading it all. Sorry, I know this is where it gets boring. :(

[crzydmnd72]

Not boring. I'm following closely!

[wake]

i check every new post on this thread..i love any kind of builds..keep up the good works..and keep the camera close

[1fatcat]

Finally got some time today, here is the latest progress.
In the first pic, if you look close, the last connecting rod has an arrow facing the wrong way. That was a mistake in the magic marker, not the assembly. I marked it wrong, but it is installed correctly.

Lower end assembled


Rear cover installed

Pick up tube installed

Front cover and stuff installed

Oil pan gasket prep. Use a sealer on this gasket, both sides



Some paint, frost plugs and pullies

[ChilinMichael]

Very nice!


Just a little sidenote, don't know if it applies for the L67, but in L36 application, FelPro puts out a new revised pan gasket that calls for only small dots of sealant at each of the four corners, it says specifically not to use sealant on the entire gasket, although that used to have to be the case but the revised design fixes that. It will say that in the instructions and also when looking up the part, they'll be a second part number or "revised part" marking.

I like the white.

[LeSabreUltra]

I like the white too, but man you are never going to be able to keep that clean lol!

I was thinking the same thing..."OMG, He painted it White!!"

Just out of curiosity, what kind of paint did you use? If it is an automotive urethane with a couple of clears on it, it might last for a while and clean easily, though it will change color around the heads.

[2000Silverbullet]

It has a very professional built look to it.
My guess is the Fiero is white also.

[harofreak00]

I'd imagine that a mid engine car can keep the engine a lot cleaner than a front engine. Plus, a full-rebuild means no leaking gaskets to worry about. I bet it will look great even years from now.

[2000Silverbullet]

After 3 years the Grizz engine I rebuilt is still leak free and as clean as when I lowered it in.

The only leaks are from the trani shaft seals. About 2 tablespoons every time it gets shut down.
