2003 Toyota Camry timing 4Clyn

Asked by Mar 01, 2017 at 12:23 AM about the 2003 Toyota Camry LE

Question type: Maintenance & Repair

Today the Mechanic tested where the spark plugs
go and there was no pressure, he believe the timing
is off, bad, or the timing messed up the valves,  I'm
hoping the Timing chain doesn't interfere with the
valves! I'm seeing different answers ! Someone help
so that way I know whether to spend the money to
fix it or not. The car over heated but I quickly pulled
over and turned off the car ! A sensor went bad
(which was the ECT sensor) and it cause the car to
over heat but when I changed the sensor the car
didn't want to turn on because I believe of timing .

I believe the head gasket blew. If it was running until the engine overheated then when did the timing chain break or let the timing get out of adjustment. When these engines over heat the head warps and lets the gasket blow, the compression can escape threw the sides or to the oil pan or to the cooling passageways. The engine over heating does not affect the timing chain it does affect the head gasket. When you fix the gaskets check the timing chain. Heads need pressure checked for cracks, if passed resurfaced and if miles are high rebuilt. Everything that comes off needs a new gasket which comes in a upper gasket kit.

If indeed you have low or no compression(pressure) in the cylinders you have a major issue. IMO...the cylinder head should be removed and an inspection should be conducted. I agree with enginecreator....Head Gasket failure is most likely the root cause of this issue. Why not call a few repair shops and ask for estimates for a head gasket replacement for your make model year vehicle? Get back to us with results.

The timing chain is still in place ! The heads weren't moved or damaged by the chain,the gasket did melt and turn plastic and the spark plugs were no good

It is possible that the chain slipped but zero compression on all cylinders means the engine is dead.

Do you think there might of been no pressure because there was motor oil where spark plugs go and the head gasket was shrunk and melted, which probably where the pressure went through?

Compression can leak out the bad head gasket.

Since it appears the camshaft cover has been removed....I would be tempted to rotate the engine by hand until #1 piston is on top dead center and the timing mark on the crank pully is lined up at ...0. I would watch both intake and exhaust valves to make sure they are fully closed. The timing marks on both cams should line up as per spec. I would then pressurize #1 cylinder and see where the air leaks out.
