Oh my , To start with take the vehicle back to the repairing shop/person it needs to be inspected chances are the timing belt or tensioner failed. Ether due to improper reassembly or part failure resulting in what you have described. The water pump should be also included in inspection, As it is driven by the timing belt ( they do wear out ) causing excessive play in the timing belt tension... Hopefully the head/ valve have not been damaged. I will hope for the best for you. Good Luck ... Kam

74 bonniville only runs on left side,new boyer ignition, new coils 6 volt ,new wires new gas and filter

Only one side of engine runs? Could be a head gasket problem on the right. It is a mechanical issue, not an electronic or electrical possibility as in newer cars. Do a compression test of the engine to see if the right side has compression failure from a bad head gasket.
A 1974 model would be a 12 volt system, not 6 volts. The last 6 volt systems were in the 1950's. If your coil is 12 volt and the left side runs and fires good, there is nothing wrong electrically. Check for spark on the right side, it should have spark on all cylinders if good spark on the left side. If no spark on the right side,. maybe a problem with the rotor or the distributor cap.

I recently changed the head gasket after overheating. The car is not starting and emitting heavy smoke

How hot did the car get before you had to change the head gasket? If the car had extreme heat then it could have damaged the rings. The rings will collapse and allow oil to squeeze past and burn out of the exhaust causing the smoke. Also since the rings are collapsed the vehicle will have no compression hence the no start. First thing is do a compression check.

2002 jeep liberty, 3.7L. 220,00mi. cyl #2 missfire, code 0352. have no spark, no compression, #2 cyl. all others 180#.

If there is no "0" compression then I expect that the spark will not reliably fire resulting in the Code 0352 misfire.

The real issue is the loss of compression!!

Unless you are a skilled engine mechanic the diagnostics of determining the root cause , head gasket, cylinder or valve will not help much.

If the car is still drive-able take the car to a qualified engine service technician and ask for an estimate to either repair or replace the engine.

No compression is never a small problem!

Do you think head gasket?

probably not --
have a compression test done to check for head gasket and cracked head
from your description I suspect that a welsh plug has rusted out and the steam is from coolant on the exhaust manifold
have a cooling system pressure test done to see if it is leaking along the side of the block

Why is there no compression in engine on my 1991 mitsubishi pajerno

This has to be because of a mechanical problem in the engine. Possible sources are the timing belt is broken (one indication is the starter spins the engine faster than normal, because the camshaft that opens and closes valves is not turning with the crankshaft), or the head gasket has failed (from overheating as the most likely cause), or badly worn piston rings and/or valves not sealing well (common on high mileage engines).
Compression is built up in the upper part of the cylinder where combustion occurs, so leaks or lost compression are due to valves not sealing, or head gasket that seals the cylinder head to the engine block-sometimes the aluminum cylinder head can warp due to overheating, and the head gasket no longer can maintain a seal. Or also the piston rings are worn so bad that compression will leak past them into the crankcase. For valves or head gasket, the cylinder head has to be removed and repaired. For the rings, the engine has to be rebuilt entirely.
First check if the timing belt is still intact.

I have Ecort 1.8 td from 2000 Y of production, and have white smoke on pipetail and idles very roughly, engine coolent is OK, oil level is OK, what can it be the problem?.

Even though coolant level is OK, it does not rule out a blown head gasket-has the engine recently been overheated? You should get engine compression checked, to see if you have low compression in 2 adjacent cylinders, to rule out the possibility. White smoke and very rough engine performance point to a blown head gasket, however.

My 2002 ford explorer engine stopped getting compression on one side. i was told that I now need a new engine. can the one side be repaired, or do i need a new engine?

That depends if the problem is with the rings or the valves or the head gasket.

Rings == engine

valves == valve job (remove both heads and take to a machine shop don't do just one)

Gasket == replace head gasket on that side.

White coloured engine oil, overheating

White oil means water or coolant is leaking in via Head Gasket Failure or a crack in the head. Along with repair - be sure to have each cylinder compression tested to see if there is a crack that has developed.

Head gasket

The best solution? Remove the heads, have them planed to true them up and put new gasket set on. Depending on how many miles the engine has on it, it may be needful to have the heads reworked. New valves guides, the valves ground and seated. If it has a lot of miles it could be best to purchase a set of remanufactured heads. If the engine is low miles a gasket set and planing the head will probably do it. If you just have one head plane, make sure to get the proper gasket for that head. The planed head will cause that bank of cylinders to have higher compression then the other non-planed side. You will have to get a thicker gasket for that side to keep the same compression. Your machine shop can tell you how much they took off. Hope that helps.
