by the way, if it is bad rings...
the only constraint for finishing a top end rebuild in time for Hershey in April is machine shop wait time. I know two machineists in town that can deglaze and score the cylinders. Get rings from Jake. Your bottleneck will be heads if (okay, when) they need work (which they will if its valve guides). Options options. this need not take all summer if it needs a new top end. But, i'd start calling head shops now and asking about wait times. Zach |

Way off the deep end, but did you check the oil pressure switch? if its loose
it will cause a problem of splashing oil around. It's located by the distributor. |

The switch would not pump oil in to the air cleaner... You will find you have low compression when you do the check.

It's located by the distributor. i do i still have the switch? yes, it is factory installed. Look for the wire coming out of the cooling tin just beside and behind (toward the rear of the car) the distributor. The wire is green with red stripe if I recall. |

I just finished the compression test..... drumroll......
#1 107 #2 97 #3 120 #4 120 Keep in mind, i just did my first valve adjustment, by myself. Zach came over and showed me the ropes... ....Thanks Zach...... ....so I either did somthing wrong or the left side of this engine is BEAT. Do you think i should attempt to adjust the valves on that side again or pull it? I am pretty sure i did a good job on the valves, note to myself (always have valve cover gaskets when doing adjustments, PO had some kinda silicon there, and i dont have anything to put back on em yet. Small mess on the garage floor, but that should not effect the compression right. lastly give me an opnion about lucas oil additive i just bought 2qrt. Dont do it or what. I figure get new gaskets add lucas, drive it for 100+ miles and do another test. (IMG:style_emoticons/default/confused24.gif) can someone slap me I am trying not to pull this engine (IMG:style_emoticons/default/chair.gif) (IMG:style_emoticons/default/chair.gif) (IMG:style_emoticons/default/chair.gif) |

Well, since the two on the samer side, 1 and 2, are low I would consider that ther head may have a problem in seating, twisting, etc. Did you check the head nuts on that side for tq? Is there any reason you should have bad rings? Did you put a tsp of oil in the bad barrels and then recheck to see if that improved the numbers? = bad rings.
Just a few thoughts (IMG:style_emoticons/default/smile.gif) |

Just a few thoughts (IMG:style_emoticons/default/smile.gif) i have not tried that... i will try it later, grocery shopping first. i was thinking in my mind somthing was wrong there, do rings usually wear equal all around or does it seem very likley that 1 and two could wear much faster than 3 and four?? |

The combination of oil in the air cleaner and low numbers are pretty much all you need to know. You need to do a top end rebuild at the very least.
I haven't been around these motors as much as Type I's, but I have yet to see a motor that had bad rings that didn't have a bad cam. |

Ah ya, if you are getting oil in your filter you are pressurizing your case via bad rings. Time to pull the 1,2 side and at teh very least put new rings on. Thats is all else is OK.

I would think it unwise to do just the 1-2 side. If you are gonna bother you might as well do both sides, get the heads looked at, check the cam for wear, etc...
