Number 7 started at 130 and worke up to about 150. Number 8 started at about 90 and worked up to about 125. I put a couple of shots of oil in the number 8 and did not get a change. I did do the test with the engine cold because I have the carb off and Im waiting on some parts but I wanted to change out the plugs and get ir ready while I was waiting. should I be concerned. I don't put alot of miles on it so I was planing to run her till she wouldn't run any more but I need it to run ok in the process. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | You have a weak valve on #8 cyl. but like you say you just want to run it a while, it will run a long time like that. If it is an auto trans. you will get a shake at idle in drive. With a manual trans. you probably will hardly notice it.
They say money can't buy happiness. It can buy old Chevy trucks though.
