The only thing left is the cam lobe it self. Run all new plugs for just one week. Pull the plugs - laying them out each plug for each cylinder - -mark them. Change them to NEW again - in one week - pull them and compare them with the new plugs. Some times you just get back plugs too so if you want to short cut it - change the plugs say - that cylinder with number 3.
Also - how old is the timing chain? This happens a lot with stretched chains - That is an old engine so I would seriously consider the timing chain being stretched. Inspect it as a precaution. I would replace it if you do not remember when it was changed to the month and year.

it sounds typical of a blown head gasket which would account for the excessive pressures

Model, make, engine?

Wrong timing or excess carbon build up on the pistons and or valves are the most common causes!

this info should be on the old alternator, something like 12V 60amp
Look on the back of the alternator for this info

Depends on milage, and condition. I got an '89 short box, regular cab, 4 cylinder with NO rust at all, but over 200,000 miles. I paid just over three thousand, as the odometer read that it had 84,000 miles on it. So I got a raw deal there, but the truck is clean, so I rebuilt the entire drive line, engine, transmission, rear end, transfercase, and on. Now I have a rust free solid good running truck for under seven thousand, that runs like new. But...I do have a lot of time in it.
I love the truck, they are well built, just prone to rust.

What it says on cap.

Could be motor mounts, or transmission mount. How old is this vehicle?

Yes

Before you set engine timing i recomend that you check for trouble codes. You can do this by jumping TE1 and E1 whitch on your engine is a round 2 wire plug on the drivers side, by air box. if you have a code then have the problem fixed, because some codes will effect engine timing. You must have the TE1 and E1 jumped when timing engine. The engine timing marks are on the oil pump on the front of the engine,down by the crankshaft. Timing is set to 5 degrees advanced(factory). Also make sure you have no vacum leaks they will also effect engine idle 900rpm which is the setting for setting the timing at.

Also make sure your engine distributer cap is good and same for plugs and wires. I hoped this helped.

Also timing chain strech which will affect timing.

hello, it sounds like the alternator is the problem, most auto parts stores can check the alternator/charging system at no charge without removing it from the truck, I'm sure you will find that the alternator needs to be replaced.

is it petrol? if yes change ht leads and coil pack. misfire should clear.

replace the globe as it may be burnt out.
