motor rebuild ?s

[Raist103]

ok going into this myself so far and i am going to get as much done as i can in front of my apt before they start asking ? as to why it is not moving.
the bottom end i plan to have someone else do or if money and time does not let me i will have to do it myself.

i need a list before i start to rip apart though.

ok i got everything but the crank forged"no $ for that" i am hoping that every thing inside is still fine and i just have a blown head gasket. now going on that thought, i pplan to change the bearings-main and cam, oil pump, and gaskets as of now.

what i will need is part #'s or if someone is selling or has extra let me know of

i know i need head gaskets right away- 1203, or something for the vortecs. getting them port matched to the intake as soon as i get the gaskets. jegs? summit? syty vendor?

what oil pump is everyone useing with a build such as mine and part # and where to get.

lifters- just stock replacments or should i go with something else?

what else should i change or look at while i have it apart again?

What is the problem? Why are you tearing into it?

what i think happened was a blown head gasket the other night and i have had low oil pressure for some time and was planning to pull the pan and check the pump and bearing but now since i think i blew the gasket i figuired i should just pull it and check everything at once.

by the other night i mean i was at the track and when i got about 3/4 way i thought i blew the turbo smoke everywhere from behind me. when i pulled to the side and checked antifreze was leaking everywhere out the passanger side . could not see so well since it was dark and the ic was in the way and have not had time to check it out yet but that is my best guess.

antifreeze all over the place, that could also be a freeze plug with a hole in it.

 

[Raist103]

side of the head you mean? would high boost have one come out?

 

[dourtyb]

If its just a head gasket you will need:

1. head gaskets: GM part # 14097272 ~$35 each from gmpartsdirect.

2. Intake gasket: I use the Felpro 1268 with my vortecs. Not sure how your intake is done. Others use teh Felpro 1203 with good results. I haven't seen this gasket.

3. Black high temp RTV for the lifter valley, thread sealer for the head and intake bolts, and some anti seize for the exhaust bolts.

4. ARP head bolts. I used the V8 set with no problems. 134-3601 is the part number. Don't re-use the stockers

5. power steering pulley puller

6. patience.

Just did the last weekend. See this thread...

I think that pretty much covers it.

ok now i am confused. i went out to check it with it being light uot and as soon as i pure water in the rad it comes right out. i jacked it up on both sides but can not see where it is coming from. if i had to guess i would say the middle of the block? i dont see how though. nothing fromt he head gaskets and nothing from the upper or lower rad hose. when i jake the pass side it looks to be coming straight down and running behind the front diff"running of the back of it as if it was leaking just above it. then i jaked up the drivers side and it looks to be coming straight down from the middle on the inner corner of the a arm, and the side of the pan by the oil line.


am i missing something stupid or does it sound like a cracked block, which is my luck.

Yes a freeze plug could have come out, it happened to me with a new mccoy motor, we put about 250 miles on it breaking it in and every now and then I would jump on it a little bit more and then the one under the drivers side motor mount came out, so I had to take the motor completley back out to fix, so needless to say i changed them all and put a coating of jb-weld around the surface and then pounded them in, They better not come out again, this is florida so I dont think I need freeze plugs.

 

[Raist103]

oh i do have the pass fender out and can see the one plug by the spark plugs and it is tight. but it is weird as soon as i pure it in it comes rigjht out like the rad is leaking but it is to far back to be the rad. and i did not see the hoses leak

 

[FLSY2730]

There is about 8 freeze plugs in the motor, you have some in the front, 2 behind the flexplate, the 2 in the front by the timing chain cover could be leaking, some are impossible to see unless you staer taking parts off the motor.

 

[Raist103]

also thought maybe water pump?

There are two freeze plugs per side in the block so the one you cant see may be leaking or has popped out.

If the coolant is leaking out in about as fast as you can pour it in wheather the engine is at operating temp or cold then IMO its prolly a freeze plug.

If no leaks are noted until the coolant heats up to normal operating temp then it could be a crakced head, cracked block, leaking freeze plug, blown head gasket, or any/all the above.

 

[Raist103]

i can not start it since it holds no water. and dont want to try and start it while someone pures it in. but yes cold pures right out

 

[FLSY2730]

Its got to be a freeze plug then.

 

[FLSY2730]

Why cant you start it without water, just for few seconds will be okay, I thought I read somewhere that top fuel dragsters dont even have a cooling system at all, no water in the motor, no radiator, ??

 

[ed hess]

don get some spray type foot powder. spray everything with it. the foot powder will be white dust color. desenex works fine.

pour water into radiator. then you can take your good old time finding where the water came from. as it will leve a tell tale trail in the dust.

harry anderson told me this trick and it does work when you cant find a leak.

ed thing is i would be able to see where if the fan and shroud were off so i think after the mustang that will be the first thing, pull those and look again, since it is puring out i should have no problem finding the leak as long as i can see.


i did try and start it just a bit ago and it cranks but did not turn over, may just be that i needed to give it a little gas but since it almost 11pm and i still have the exhaust open i did not want to try any further as long as i know it is not seized i am fine.
