Generally you want to make sure cylinder#1 is at TDC before replacing the timing belt.
4AGE was produced through 1991, so you're looking at a motor that is 24+ years old, and potentially a number of aging/wear and tear problems.
Now, you and the mad scientist got to rip apart the block... and replace the piston rings you fried.
If the static timing is correct(the relation between the crankshaft and the camshaft it will have compression regardless of whether the distributor is installed right or not. It sounds like you might have messed up the static timing. If you moved either the crank or the camshaft while the timing belt was off then it will not run right(if at all). If it ran fine before you did the belt I doubt the head gasket is bad.
If the crank shaft is 180 degrees out compared to the cam shaft, it can cause that problem. I am not sure of the firing order on that engine and too lazy to look it up for you. If the cam shaft is 180 degrees out of time, that will not effect the compression. If the cam shaft is 180 degrees out of time, the distributor will be out of time and the engine will not run unless you rotate the spark plugs 180 degrees, but that will not affect compression.
Out 180 degrees ignition timing YES you will have compression. Out 180 degrees on the timing belt we need to know the year, make and model of your car.
it will but it would backfire badly. if you have one at 100 psi and the other three are low, look into a different issue like a cracked head or a failed head gasket.
Try timing it according to the repair manual.
The timing is out. You need to do it again.
I recently did a timing belt on a 4age (toyota motor). I remember looking for conpression before setting timing up...but it is possible I messed up...
My question is will 180 degrees out of time motor make conpression?
My numbers are 60-50-40-120
I want to say bad headgasket, but loosing close to 100 psi through head sounds off...
The car will also occasionally backfire when trying to start...
Please any advice appricated.
