302 - ticking - Input required
Hello all - first time posting in this forum.
I've got a nice little 79 F-150 (as can be seen in my gallery) and I would like to ask a question about the little <a href="http://motorhaven.autoanything.com/">302 </a>it has.
It is making a ticking sound under the passenger's side valve cover - has been since fall - not getting much worse really, but is most noteable when the engine is cold. Once it warms up, it isn't that noticeable - the average joe wouldn't notice.
What is the prognosis and what is the cure?
(please no responses saying to slap a stroked rebuilt <a href="http://motorhaven.autoanything.com/">460 </a>in!
- I've got a spare <a href="http://motorhaven.autoanything.com/">351m </a>if I need it in old blue - the infamous parts truck - also in my gallery)
Thanks!

yeah, it's definately screwed. You should look into putting a GE F404 Turbofan jet engine in it, or at least a bored and stroked <a href="http://motorhaven.autoanything.com/">460 </a>with a monster cam and loads of <a href="http://motorhaven.autoanything.com/">nitrous</a> on it. Do that first, and then we can talk about your supercharging options.
Seriously, you might have a rocker arm that worked it's way loose. Just take the valve cover off, and wiggle each of the 8 rockers under that cover, and see if any of them feel loose. If you find the one you're looking for, then tighten the nut holding it down back to around 25 ft*lbs. If that's not it, you could be looking at a minor rod knock, mine sounded like a rocker arm tick for 6,000 miles until it got very loud because I was losing oil pressure.

Yeah, that's my kind of "fix".
But seriously folks...
Also check for an exhaust leak. It's suprising how much that will sound like a lifter.
Just my 2¢

Thanks for the Turbine tips guys!
Seriously, thanks for the tips on the rocker arms and checking for an exhaust leak (any thoughts on common problem spots to check).
I don't think it is a rod - the bottom end has been re-built (new crank, etc) and it was done by a pro.
Oh, and I've put on about 10,000 k.m.'s since I first noticed it.
Hopefully I will get to it this week-end.
Thanks again!

I just went through this with my 1987 F150 w 351w. Befor I go into what it was a number of people told me to check if there was an exhaust leak somewhere. it seems that an exhaust leak could sound like an engine problem. Anyway I had a problem with one of my pistons. i would check for the exhaust leak first and make sure all parts of he exhaust system are tight.
