DIY - Tercel 91 - 94 Valve Cover Gasket Replacement

This DIY is on a 1993 Toyota Tercel with a 1.5L FI SOHC 4cyl , 3E - E .

This is the Valve Cover gasket with Grommets . Best thing to do before you start this job is to power wash your motor especially if you have a leak in your valve cover and want to make sure you have correctly fixed it .

First thing I did was remove the PCV valve hose to the valve cover then I removed the two nuts holding down the valve cover .


Once you remove the two nuts with a flat head screw driver gently lift up the valve cover till the grommets come up then remove the grommets then you can remove the valve cover or you can remove the intake hose going to the intake to make it easier when you put the valve cover on .

As you see in the top photo how much better clearance you have with the intake hose off . In my case my valve cover was rusted and nasty looking so put a rag that is dirt and lint free so if any wind doesn't blow dust or sand in your cam shaft area . Then you can clean up your valve cover from grease and clean the area on the head from grease . In my case I repainted my valve cover .

Once you finish painting or degreasing your valve cover you can add a little of gasket maker silicone inside the valve cover . Some people use the gasket maker some don't its your vehicle you decide how you do it in my case I used it . Once you apply it on then you put the valve cover gasket in the groove and gently press on in flat then find a clean surface to rest the valve cover on for about a minute or two so that the valve cover can get tacky and lay flat .

Once you have waited in my case I added just a little of the gasket maker on the bottom of the gasket again its your car if you want to or not is fine . Then you hand add the NEW grommets - DO NOT USE THE OLD GROMMETS because once they have been used they are no good any more because the squeeze flat . Then you hand tight the two nuts go side to side so that it lays flat then you hand tight till the nut stops and the grommets are pushing the valve cover flat . Then you put every thing back into place .
Let your valve cover sit for about five minutes while your cleaning up your area then you can start your vehicle and look for leaks . Wait about a week or two weeks then just check lightly that your two nuts on the grommets are still secure plus the rubber shrinks after it is heated .
