This doesn’t look good...

Previous owner must have cheaped out on the oil or didn't observe appropriate service intervals. I lived in Killeen for 20 years. Can't say I miss it.

I get chills in my up and down my spine when I hear people say, "i've been using the same oil for years with no problems"…........

I added this to my “break in" and "post break in" oil change ...

about 1 ounce per quart of oil.

[brianmac]

does the head have to come off to do the lifter replacement?, and if so, what gasket are needed or not needed?

[davej]

No the head don't need to come off. Just the rocker cover and rocker spacer plate. The plate has to come off to remove the pushrod tube to access the lifters.

Gaskets are metal and reusable. Just don't bend them [obviously] and wipe them clean, along with the mating surfaces, before reassembly. You'll likely have to use a rubber mallet to break the rocker plate free from the push rod tube. Go easy; the tube is just held in place with an o-ring at each end. Also, *BE VERY CAREFUL* not to let the dowel pin, under the intake side of the rocker plate, come loose and fall down into the oil drain back hole. The hole is in the perfect spot for the dowel to fall in and end up in the bottom of the crank case.
