I am replacing timing cover on my 97 f150 4.6 engine. How do I deal with where it meets the oil pan? I have watched several YouTube videos in the last week and most say not to drop the pan. Do I just run black silicone along the front lip where the timing cover sets on it?
Can someone walk me through this in depth or post a picture? Thanks in advance.

 

You don't need to remove the oil pan, just clean where ALL the mating surfaces meet. Apply hi temp silicone on ALL the surfaces and a lot of it. I'm assuming you have the valve covers off. Trust me....apply silicone on ALL surfaces....both sides. Using too much is not going to hurt but using too little is asking for a leak.

 

As stated in above post...do not drop the pan.............What's important here is to have the pan lip in that tight corner really clean & dry (for the silicone to spread out/seal & stick!!)

 

Pulling timing cover tomorrow. Cam covers are ready to come off. Just want to ask one more time how to handle where the timing cover sets on the oil pad. Do I remove the section of the pan gasket that will be exposed and replace with hi-temp silicone, or leave it and put silicone on top of it? This is my first try at this,and would like to do it right.

Also do I put any adhesive on cam cover gaskets to keep them from falling off when I try to get passenger side back on. It is really tight on that side as y’all know. May try to remove and replace heater hoses if I have to. ALL advice appreciated. Maybe a link to an actual video of this procedure on a 97 f150 4.6 pickup with motor still in truck if anyone knows of a good one. Again ,thank y’all for your patience.

 

Use just enough silicone to do the job, too much can fall into the motor and cause catastrophic Ju Ju.

 

Just finished a couple days ago timing guides, intake manifold, spark plugs on the 97 5.4.
Passenger cam cover I didn't use anything additional on them. The rubber gasket fit great and the bolt washers helped to keep the gasket in. Yes it is a tight fit but do able. Maybe since I had the intake out at the time.
Timing cover gasket fit great also, used the Hi temp silicon at the cam cover, head, and the entire bottom that meets the oil pan. Only had the 4 bolts removed, I was not going to open up the oil pan.
I like this channel for F150s
Of course i had everything back together and the pressure hose from the power steering leaked. Remove and replace.......

I replaced the heater hose connections a couple of years ago, Not fun... I made a tool from scrap metal to help remove them like this.

Still looking for an answer to my question. Do I remove the section of the pan gasket that shows when I remove the timing cover? Or do I apply a bead of silicone on top of it when I reinstall the cover?

 

As long as it doesn't get too damaged, roll with what is in there. RTV is your friend in being able to reuse it.

If it leaks... it's really not that bad of a job to replace the pan gasket.

 

Thanks for the quick response.
