I had a number 2 cylinder dlown head gasket. I see pitting in the block surface but its strait as an arrow. Should i pull iy and get it resurfaced?

 

picture, and we can give you a better answer, are you running stock boost pressures, what are your plans for the car.

 

The ecote blocks r lost foam casted so they look pitted..
I believe the lsj head is sand casted someone correct me if im wrong. And i think the bed plate is sand casted also.

 

head sand casted, block upper and lower lost foam.

 

Hmm ill take a closer look at my spare block but i thought it looked sand casted..

 

you know now that I think about it, you are right, the lower section, the cradle is sand cast! sorry about that.



OP the deck of the block is what matters when the headgasket pops. We need to see a pick of the deck if you would like input on the pitting.

 

the deck of the head matters just as much as the deck of the block

 

here are my pictures my head is getting resurfaced

 

This is a close up of my zzp block

 

true but the op only stated he was worried about the block, guessing he has no issues on the head.

 

my mrbelvedere sleeved block



Freshly ported, 3-angle, decked head, ferrea valves, 82# springs, blah blah. I had this done at a diesel shop because they were the only ones with machines big enough for our 13" wide head.

 

the block and head needs t be finished as fine as possible if it isent it wont hold a head gasket and do not use copper spray on the head gasket

 

what would cause that have a bad head gasket for awhile?

 

Planning on sleeving a gen 3 LHU block.

 

can the engine and trans be pulled out the to as a unit?

 

Top? I'm not sure

Most people drop it through th bottom

 

yea i don't really have the resources to that. god i wish i still worked at the dealer. but you got to go where the money is

 

I heard that.

But you can get the car high enough with a jack & stands to drop it out of the bottom

 

LHU block doesn't have sleeves

 

Dude drop it out the bottom, I did it with 4 6-ton jack stands 3 ton jack, 2x4's and a furniture dolly.

I reinstalled with a friends cherry picker but never used the crane portion of it for more than a second to sit it in the cradle. You dont need a cherry picker or anything else but the stuff I mentioned above.

 

what you are seeing is due to the lost foam casting process and is normal

 

thats impressive!!!! Where theres a will theres a way lol

 

i was motivated and alone, built the entire engine, car, etc by myself with some cash of course. Turned out ot make 420 very reliable horsepower, or so we shall see, its only been ran hard about 12 times so far.

if mrb ok's it I would think you wont have to pull that engine.
