Hello everyone.
I have finally got around to doing the compression test on my 1967 289 4v,
To get everyone up to speed, I am getting smoke and oil coming up through the oil filler hole, the dipstick and the pcv. I have replaced the PCV and make sure all the crannies under the carb is clear.
Here are the compression results (by cylinder. I did each on twice and these numbers will be rounded off to the nearest 5)
1 - 130 psi
2 - 80 psi
3 - 130 psi
4 - 130 psi
5 - 140 psi
6 - 125 psi
7 - 140 psi
8 - 65 psi
Now seeing that #2 and #8 are so far out of norm, I squirted some oil in each hole, let it set for a few minutes and tested again. Here are those results.
2 - 190 psi
8 - 160 psi.
Here is where I need help. What should my next step be?
I have a spare motor I can rebuild. I have not done any testing on it but I pulled it out of this car because of some ominous oil burning, piston noises and loud clicking under the valve cover.
There is also a shop near my place advertising a rebuilt 302 with a 7year/70,000 mile guarantee for $855.
I am trying to minimize cost and downtime since this is my only means of transportation.
Thanks so much in advance for your help.
