Under the cam covers. 98 F-150 4.6L with 250K miles

I'm in the process of doing changing the timing chain, guides and tensioners on my 98 F-150 and I'm surprised by how clean it is internally. I bought the truck new. For the first 125K miles I used M1 5w-30 with OCIs of around 5k. Around then I fixed a blow spark plug then started using 5w-30 Super Tech. synthetic.

Looks great

I'm not surprised with the use of synthetic & 5K intervals. The 4.6L/5.4L 2V SOHC engines are very durable.

Thanks for pictures. Proves a good oci and a decent oil do good things.

Nice!

Nice pics! Thanks for posting. I'm glad to see this since I just switched my junks from M1 to SuperTech.

Looks great! Might was well change the timing chain tensioner and guides while it's apart.

Seems the SuperTech has been doing it's job... here's to another 125k miles! ðŸ‘

Looks fantasic - it would be interesting to see 250k miles, 5k synthetic OCI, on an V6 Ecoboost so we could compare.

 

[Cujet]

Very nice. A well maintained 4.6 will easily top 500K miles. They don't seem to wear out rapidly.

What oil filter brand/model, have you been mostly using the past 21 years?

 

[Blueskies123]

You should not be surprised how clean it looks. This how they look if you do the kind of oil changes you perform.

Looks good. Really like timing chain pics!

Yep! Doing the complete kit. The pics are the old chain and stuff. I was also surprised by how little wear was on them. I will say the job is a huge PITA. It took me a day just to get the cam covers and timing chain cover off.

Normally the MC FL-820-S and a few times the Fram PH2 version. I've cut a few of both open over the years and have never noticed a problem.

Did it need chains and such or are you doing them just because?

Thanks for your reply and your Service Cliff.
I had to rule out the Navy years ago. I swim like the Plymouth Rock when entering deep water.
