Honestly it could be dozens of things.
Your best bet is to have a qualified mechanic check it out.
With any luck, it is something as simple as a harness connector not plugged back in, but on the flip side, it could be engine/head damage from the blown gasket.

Are you sure it needs a head gasket? These are common for just having leaking intake gaskets and that is alot easier and cheaper to fix.

the timing chain is not correctly installed. you never just crank it over. After you install it, turn it by hand without the spark plugs in..... 2 revolutions and check the timing marks are where they should be. if you feel anything hit or it stops turning back off and figure out why, do not force it. it should turn easy.

SOURCE: grand prix has a 3.1 6cyl. and 166000 mile, it blow white smoke

Sorry to inform you of the bad news but the white smoke is engine coolant burning off and the rough running condition is also associated with coolant leaking into the combustion chambers.This will be a head gasket repair, basically a head job where you will need to machine the heads down and install new gaskets from the heads up.Get back to me if you have any more questions, thanks and I hope I could help!!!

SOURCE: how to check head gasket on a pontiac grand prix

well, you can do a compression test, but that is tough to diagnose as you have valve seats that could not be sealing,and piston rings also. The best i can do is this, 1) are you loosing coolant ? 2) Is there coolant in the oil (oil over full mark, oil a light brown milky look ? 3) pull the spark plugs and keep track what cylinder they came from, are any plugs real clean compared to the rest? regular plugs should be a light brown paper bag in color,if they are darker it is because of carbon deposits etc... But a cylinder that has a coolant leak will burn like a steam cleaner which results in a plug that looks brand new out of the box compared to the rest. Just because your tail pipe spits water out of it, it does not mean a bad headgasket. that is just condensation of cold getting hot air blown on it just like when you first turn defrosters on and your window fogs up for a minute.

Setting of timing chains


Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)

4 timing chains (3 front including the optional balance shaft chain + 1 back)

2 cam guides (1 front + 1 back)

2 oil tensioners (1 front + 1 back)

1 jackshaft tensioner (1 front)

1 jackshaft guide/cassette (1 front)

1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)

1 balance shaft guide (1 front) (will probably be ok, so dont replace it)

new sprockets + bolts + gaskets etc.

new spark plugs + throttle body cleaner + lithium grease spray + oil change

head gaskets


some of these parts (the front stuff) can be obtained as a primary timing chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for 2*4.

The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com


My parts order (without the balance shaft stuff) was:

$76.04 KIT-TENSIONER TIMING 2u3e-6d256-ab

$47.93 Engine, Camshaft and timing, Timing chain, TIMING CHAIN, Explorer, Mountaineer, Rear - 4.0L SOHC - 4.0L SOHC

$57.36 Engine, Camshaft and timing, Chain guide, CHAIN GUIDE, Explorer, Mountaineer, Jackshaft To Cam - 4.0L SOHC - 4.0L SOHC

$103.22 Engine, Overhaul gasket set, OVERHAUL GASKET SET, Explorer, Mountaineer, Upper (Valve Grind) - 4.0L SOHC - 4.0L SOHC

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC

Its worth mentioning that this procedure is not enjoyable at all and should be undertaken with at least 8 full days to completion (I recon you could do it in half the time the second time).

It is basically on entire engine re-build with both heads off and the engine out of the vehicle.

It is not possible to do the rear chain or sprocket with the engine in the car as the flywheel needs to come off + at least 1 head, but it is possible to do the front primary chain and or front cam chain with the engine in the car.

You will be a ford exploder and timing expert after you do this - the main reason should be the love of your American built vehicle. Its a solid car - except for the plastic guides!

Disclaimer Note: This is how i successfully did the job, but i am not a ford mechanic and don't hold me responsible if this does not work for you.
Timing Overview

A Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft sprocket that is in turn connected front & back to the 2 camshafts.

Thus a 360o turn of the crank will turn both the camshafts 180o.

Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.

At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.

The engine will turn freely (no piston to valve contact) with the cams 180o out, it will even run (roughly) with 1 out 180o, any other settings may cause major damage to the valves.

The 2 cam shafts come with timing markings, "yes" real timing marks that anyone can use (even without special tools) to ensure correct timing.

The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.

With the engine at TDC both the cams need to have the off centre slot in the same position either up and level or down and level.

It is super critical that both the camshafts are 100% in sink with each other, i.e. not a few degrees off, the engine computer can compensate for crank timing but not engineering failure.

Be warned the camshafts can turn easily fast & hard by themselves as a few springs are compressed at TDC, I got my finger jammed and its still healing + if the engine is not at TDC you may damage a valve.

Now heres the hard thing that you will need special tools for - if you need to change the timing, you will need to be able to undo the cam sprocket bolt on both cams & these are done up real tight.

There is a tool that you attach that has 2 pencil thick shafts that fit into the sprocket and prevent it from turning - then you need to put about 90Nm of force on the bolt (remember the rear one if LHT)

For the $money$, its well worth getting yourself the tool kit - it will save you hours in the long run. Search eBay for otc-6488 should be US $119 - then sell them again for say $100.

There is also a tool version of the oil tensioner in the kit that screws right in and puts the correct amount of force on the chain + guide, to enable you to do up the cam bolt with the chain and sprocket in the right spot on the cam.

How to replace head gasket and how to put it back in time when assembling back together on 2.4l (quad4) engine??


There will be marks on the cam gear and the crank gear. Some are dots, some are diamond shaped. You just line the two up so the top mark is directly over mark on the crank. You may have to turn the crank by hand which is easier with all the plugs out, to line it up. You will want to drain oil,change filter, and put in new oil to get rid of contaminated oil in oilpan.
If you fail, you are not talking about a lot of money to try to fix the top of the engine compared to engine replacement. For the most part, you could still tow it.
You could ask how much it would cost just to replace the gasket and let someone else bust their knuckles.

1995 grand am wont start


It sounds like you have a blow-en head gasket. The engine fills up with water and you reverse the rotation it relieves the compression so it will start. White smoke is always water. It does not take much to blow a head gasket on this make of car. I would pull all the plugs out and do a compression check. Look and see if you have water on any plug and mark that one.that will be the side it is on. If there is no water leak check the timing belt if it is a OHC. If not check the timing.
