Intake Manifold/Timing

[t_stang00]

So tomorow will tell for sure, but its most likely that it was not a blown head gasket but rather a cracked intake manifold. Yes its the stock plastic one..and yes antifreeze is bubbling out of the coolant cross over.

SO MY QUESTION:
When replacing the intake manifold, do i have to reset the timing?
or can i just hook all the new stuff back in..and it be ready to go?

Thanks!

It is just basically a bolt and go. It is vitally important to follow the torque pattern and amount (18 lb-ft). The manifold is easily damaged by over torque.

Take a few pictures as you go. This will help to get the routing correct.

Recommend a good cleaning of the engine top side with compressed air before starting (including the spark plug holes). Very easy to get debris inside the engine once the manifold has been removed. This is also a good time to change spark plugs as the access is great.

Some people say the intake gaskets are re-useable if in good shape. IMO, given the age of the car, recommend going with new gaskets. (esp since you stated in another post there is white smoke in your exhaust).

Great write up by reddaemon. Show all the steps in a lot of detail.

If you are really anal, replace the two O-rings in the coolant return hard line at the back of the water pump. You will loose some skin removing the nuts from the back of the heads supporting the hard line.

Clean the gasket surfaces to help ensure a leak free job. Do not use metal scrapers.

If the replacement manifold is an after market Dorman, the gaskets are built in.

+1. I learned this the hard way. Trust me when I say that the #3 and #4 spark plugs are a real PITA to change w/ everything still on. Extremely easy to do while everything is taken apart.

Reset the timing? Wow, you must be old school, huh? Nothing wrong with that my friend... The reason I point that out is that I remember pulling the heads (to have em rebuilt) on my 351C in my 73 Mach 1 back in high school (this was around 1983). Everything went well putting it back together, but it wouldn't start. Why? Distributor was 180* off. Lessons learned.
Remember this car has no distributor, no points, condenser, etc. Individual coils on each plug deliver huge amts of juice. No plug wires. It's a good setup.

thx guys

thx guys, its funny, i forgot to check back here before doing it.
i bought an intake manifold from autozone..and me and my friend took it apart, new one on, back together in 3:45 mins and it started first try..w00t!


but its stillsmoking out the tailpipe..and wen u rev it up high..it smokes even more..how long of letting it run before all the antifreeze is out..could it be a different problem? even tho the intake was cracked?

Do you know the history on this car? Has it been maintained well? Has the oil been changed regularily? White smoke / Blue smoke? Blue indicates oil burning, which typically indicates engine wear. How many miles are on the car?

try a compression test to see if the head gaskets are good

After my Son's truck dropped a valve, large amounts of anti-freeze ended up in the exhaust. After installing a new motor, we were very worried about the large amouts of white smoke coming out of the tail pipe. After perhaps an hour of driving, the antifreeze burned up and everything is just fine.

Bottom line, it could take a while for the anti-freeze to burn out of the exhaust. It shouldn't take too long. And you should notice it getting better as you drive.

If there is no improvement, you may not have found the source of the anti-freeze (or the new manifold leaks as well). At that point, suggest pressure testing the coolant system.

theres a reason i came to this forum
ok ima try some of the suggested things tomorow..
if anyone else has any other ideas..please feel free to say!
