Hey everyone!

I know this is going to sound stupid, but... what are lifters? I hear everyone talk about them, and I have no idea what you are talking about!

What is there purpose?

Thanks!!

Ticking from the valvetrain is never healthy. You never know what is going on inside the block unless you open it up. I know first hand, my blown head gaskets revealed bent valves, which vented exhaust gases into the crank case. The block was filthy with sludge and burnt-on oil. Yet the oil changes were always a pleasant amber color after 3k... If you don't want to look, at least flush it. The above mentioned adventure happened around 80k.

Mike, you mentioned 3 ways of using SeaFoam. I only knew about the induction variety. Could you post or point me to the directions on the other two? (gas tank + crank case).

Thanks!

One in a tank prior to getting out on the road for a good drive. I don't remember mentioning a third way. As for the crank case, if there is a problem I prefer the ATF flush, if no problem the a cquart of engine flush every three oil changes works great.

Mike is right again.
Tick is internal. I'm going to call the dealer. Hoepfully they won't give me the run around since its a 240mile drive to the dealership. At least they still pick up. I'm at 65k with a 100k warranty. It's been ticking since I got it at 18k first time I brought it up they said it was normal and probably the belts. I don't think anyone actually looked at it. Do you think the tick could have led to the tap??? I might have to swap back in the stock exhaust so there will be no doubt about what is being heard.

yeah i have a 2004 Disco 2 with 20,900 miles and my engine gets pretty loud until the engine is fairly warm. I am under the factory warranty still and an extended warranty. I am gonna get my oil changed again in early november (i changed it a few weeks ago and i hardly drive it), should I have the dealership investigate the problem sooner?

Probably. I dumped heavier oil in there fearing it might be somehting I did. I normally use 5/10w30. I used a 0w30, Synthetic that was supposed to be thicker than any other oil I put in the Disco. The first couple days were good, then the tap took longer and longer to go away and then I was getting the tap every time I accelerated. I know I was not low on oil. I checked the oil constantly. So I dumped it at 1600miles and put in a quart of oil stabilizer and 10W40. It's now kind of like it was before. A little tap on start up until warm. I can still hear it 20 minutes into my morning commute but I have to be really listening, because now I know its there, I can pick it up in an instant from inside the truck. Can't imagine what it sounds like from outside. When it gets louder again I'll send it to the dealership. I wanted to make sure it was not a false alarm because its a 500mile round trip to and from the dealer.
I also have an internal tick. I can't really hear it from inside the engine. Ii is distinctly differnt from the tap I get. The tick is sharp like a clock, and the tap sounds hallow. If I were closer I'd take it in. But I'll have a laundry list of things for them to look at when I take it in.
