Extra hole in new cylinder head. how to plug it?

I recently bought a new cylinder head for my s10. After I installed the head and started reassembling it I found an extra hole on the intake side with threads near the horseshoe bracket. I looked at the pictures of the heads from O'Reilly's which is where I got it from and there was no hole. I am thinking it is an alternate coolant port and rather than taking it all back apart and reinstalling another head I would rather just plug the hole and I am wondering what I could use. I found a "Cylinder Head Oil Plug" on the jcw website and I am wondering if that is what its for. Please help. I just want my truck running again soon and I don't want to have to take everything back apart just because of a hole.

SOURCE: intake? coolant leak

This is a common problem with this engine. The gaskets between the intake manifold and the heads need to be replaced. This will require other gaskets, seals and o-rings. Fel-pro makes a intake gasket kit that comes with everything "gaskets and seals" in it. Ask for the perma-dry gasket if available.

next step is to remove the intake, you are on the right track, worse i ever found was a cracke block, but that was in a 61 t-bird which was repaired with jb weld ten yrs ago and still holding, but the intake gasket sounds right

I have a 2000 Volkswagen Beetle 2.0 5 speed the number 2 cylinder keeps blowing the spark plug out of the hole what would cause that and how to fix it?


The spark plug should not come out if it is the proper application spark plug with the correct torque. Sounds as if the plug hole may have damaged/stripped threads which can lead to a costly repair. There is an alternative repair for this without removing the cylinder head. A Heli-coil can be installed into the damaged plug hole. If installed correctly, this repair can last the life of the vehicle at a fraction of the cost

Can you put a 5.4l cylender head on a 4.6l motor with a 4.6 cylander head


Obviously if you have the bad head off, you can compare the two. The extra .8 could be made up in piston stroke. So if the holes all line up, I would go for it as long as the two match in all aspects.

Put on a new timing belt now it wont start


I need some clarification. Did you replace the belt because it broke? If so you may need to replace the head. The problem is if the belt breaks when your moving it usually damages the head and thus needs to be replaced.

Remove plugs bmp engine over to see if coolant comes out plug holes .Do compression check on all cylinders. Check rear of intake it is common for a leak there.

S10 lost serpentine, now no-start


Hi I am Vortash sorry to hear of your problem .. Kids lol got to love em ? lol .. sorry to say but the compression readings are far too low minimum should be 140 to 150 psi per cylinder .
now you say it was the power stering belt that went , this on it's own should not have caused overheating at all unless the water pump is also driven by this belt ? then I am afraid it is possible you cooked your head .. you will need to have the head removed and pressure tested for cracking .. there should be no damage to valves as the timing belt did not break .. so therefore the pistons would not have hit the valves at all unlike your wifes car .. again got to love em lol ?.. But this test will determine if the heat has damaged the valve seats .. you will probably have to have a couple of thou machined off the head and a new gasket .. My advice is to obtain the Haynes Manual for this car it will tell you the best way off dissmantling and reassembly and save you time and money .. hope this helps regrads Vortash

The car's peformance has been poor, especially on picking from a stationary position (no power).


I would suggest to have the pump timing reset and probably have a diesel specialist to check the pump as well. It is very difficult to give extra help over the net as most of the things have been covered by the mechanic I supposed. But as per your description I think the pump may have not been timed properly or it may need overhauling as well.
Cheers

2003 S10 over heated. Now it will not start


In general, blown head gasket will cause the car to overheat then not start. Do a compression and leak down test as well as checking the plugs, cylinders ( try to peak in the hole to look for coolant) and check the coolant level. if the head gasket is blown it will consume coolant.
