1997 Ford Escort Problem with cold starting

Hello kevps Welcome to 2CarPros.com An engine starts normally when cold, but has hot starting problems. Check the residual pressure of the fuel system when the engine is shut off. If the system isn't holding residual pressure, the fuel inside the fuel rail may be boiling from the engine's heat. The cause here is a leaky check valve from the fuel injection supply manifold or a faulty fuel regulator. (see pictures)

Unscrew the fuel pressure relief valve from the fuel injection supply manifold, replace with new one. Install the valve and tighten it to 70 inch lbs. (8 Nm). Connect the negative battery cable. Run the engine at idle for 2 minutes, then turn the engine OFF and check for fuel leaks and proper operation. if replacing the relief valve does not solve the problem, than the problem is with the fuel regulator.

Now back to your other question . definitely they are talking about the intake and exhaust valves. Cleaning the valves and putting them back won't solve any problem , maybe for awhile unless EGR system have been checked and repair if found faulty.

If you read what I wrote properly you will see that I never said there was a hot starting problem.

Hello_

Your engine suddenly quits running, but then starts again and runs normally when hot,in that condition cleaning the valves and putting them back may help . Verify that your engine is not burning oil , because that cause heavy carbon deposit on intake and exhaust valves or other combustion chamber deposits that do not respond well to normal levels of detergent in gasoline. Additional cleaner is needed, which can be added to the fuel tank or run directly through the injectors.
if the oil consumption is high, because of worn valve guides or valve guide seals, it is possible to replace just the valve guide seals without having to remove the cylinder heads or overhaul the engine. New valve guide seals can drastically reduce oil consumption.
that may save you money.

It's not burning oil.I check the level when I do my weekly check and it's always on the level.[quote:1b3477be66="mathiaso"]Hello_

if your engine is not burning oil, then the deposit you mention in your earlier post must come from other combustion chamber deposits that do not respond well to normal levels of detergent in gasoline.
