Question about 1997 Toyota Celica

1 Answer

I am putting a Japenese pullout engine into a 1997 Celica, The *** engine is not drilled for an EGR valve. This is a 7AFE engine 1.8L. The company we bought it from says we need to drill a hole in the head for the EGR valve. I would like to know the best way to do this. For example is there a drill guide for this application. The hole on the old engine looks about four inches deep. We didn't want to start drilling without some advice.

    What happens if we run the engine without the EGR valve attached. I assume the check engine light would stay on all the time.

I honestly have not read or seen an aftermarket drill guide for such a process. I would recommend taking the old cylinder head and the new cylinder head to an automotive machine shop that specializes in cylinder head refurbishing and asking them to perform the operation. They should have the milling equipment to perform the task. If the hole is not drilled at the correct angle and depth, the head could be ruined.

    Yes you will get a service engine light on. You can try to drill it yourself, but no guides are available.

How do I fix an EGR problem for a 1997 Mercury Mystique?

What you would need to do is find out which part is making the problem. By this, I mean the electric solenoids which supply Vacuum to the valve or the EGR valve itself or the EGR ports feeding the exhaust to be recirculated.

Free "check engine light" tests are available at major parts stores like Autozone.

You can test the EGR diaphragm by using Vacuum or by pushing the diaphragm open and putting your finger over the vacuum opening and sealing it off.

You may also have soot in the EGR valve prevent it from closing. Remove and clean the EGR.

How to remove egr valve on 1997 lincoln towncar

The EGR valve can be replaced by using a pipe wrench, or a standard wrench to remove the fitting over the pipe going into the EGR valve... it's not too hard to replace, I've done it on mine myself... I have a 97 town car as well... the only problem is that my EGR valve was fine, but the computer told me it was bad... But I found out that the EGR sensor was bad, not the valve... now to replace the EGR sensor you need to remove the engine... FORD in their infinite wisdom decided to put the EGR sensor on the rear of the engine, half way down next to the firewall...

My mechanic said that as long as the car is running fine, I souldnt worry about the EGR sensor, its job is to tell me when the EGR valve is bad...

Hope this helps

Hi, check your valve lash your lifters are not hydrolic, on 7AFE motor valve lash should be done cold and set at 0.15-0.25mm for intake and 0.25-0.35 for exhuast.  On the 5SFE motor set cold also is 0.19-0.29mm intake and 0.28-0.38 for exhaust.
