Maintenance & Repairs - September 2007

What is the maximum compression ratio I can run before I have to start using higher octane fuel? I found a chart that says anything over 7:1 must use 92 or greater octane rating. However, I just read an article with a builder that used 9.1:1 pistons on 87 octane. Someone want to clarify on this for me? I've also been trying to figure out all of the particulars of a camshaft. I understand everything that can be changed on them, but I don't know how all of the variables affect power and drivability. For example, I was told not to use anything over 230*/230* duration if I wanted to keep the engines drivability (which I do). Is that accurate? What is the maximum overlap I should look for, and how much lift on the cam lobes should I look for?

Ok. My Brother and I were working on my 81' El Camino.

I forgot to remove the battery cable. Apparently the carb'ed 305 took the place a fuel injected motor maybe... becuz the wiring harness had massive amounts of plugs unplugged. and you only need the basics for a carb'ed car. one of the plugs arc'ed and the car hasn't been able to start since. I think it fried the starter, I replaced it. Still no go.

I have a 22' trailer weighs about 4500 lbs. Tow it with a 2000 Escalade which is a Denali with different emblems. I have heard that because of the gearing in a SUV as apposed to a pickup I will likely lose my transmission if I keep towing with it. Is this true? If it is what would be the solution? Lower gears in the front and rear differencials? A shift kit in the transmission? Or changing the transmission to a medium duty truck transmission?

by a cop, if you get a ticket, how much is this ticket worth, or is it just a ticket to get you to go fix it and no fines are attached to it. doesnt make sense levying a fine on someone who didnt know one of his headlights failed.

I have a slow leak which is coming from the the bottle which holds the power steering fluid, and do not know whether or not to use a sealant similar to radweld, or if this would cause problems as it would mix with the power steering fluid.

I have a 98 CR-V with a bad air conditioning compressor. Can it be replaced by a do-it-yourselfer with a friend who is very handy with cars? Do I need any special tools or equpment? Is it better to buy the thing and have a shop install it? Thanks.

Recently I've noticed that when I start up the car, it idles up and then really low like it's going to shut off. Also, when I drive it hesitates when accelerating, sometimes to the point where if I put the pedal all the way down, it won't accelerate or if so it bucks then accelerates. It seems like over the last several months, the gas mileage has been getting worse. About a month ago I put some gas treatment in it but I can't see where that's helped. Could it be the fuel injectors, spark plugs/wires, fuel pump, sensors, or what??? I'm afraid to drive it cause it may not start again or shut off on me.

I was driving it fine earlier. Parked it and left, using it and the reverse worked fine. When I noticed when I got home, i tried shifting it into reverse, it wouldn't do anything. It was like there was never a reverse. Its a 1986 MR2. All the other gears work fine. I can shift into 1st - 5th, just not reverse. Need help ASAP. I need this car for school

I just changed the wires and plugs on my 94 buick regal 3.8. The wires are all connected correctly and the plugs are in tight, with the proper gap. However since I have changed them the car is idling pretty rough. It goes away as I drive, even at low speed, any ideas? (Also, It used to idle rough every once and a while, but is more persistent since I changed the plugs and wires.)
