Rich,
I tried to add a pic in a p.m I sent you but could not do it. Can anyone tell me if looking at this pic there is an indication if the valves are burned or bad?The car has low compression and is near impossible to tune.The pic is of cylinders 1 and 2. Thanks.  |

Unless there's a wedge shaped hole where the valve is burned through, there's not much you can tell without removing the valves and measuring them, as well as making a visual inspection of the seating pattern. Odds are, if they have a lot of miles on 'em, the stems are worn. The intakes may be able to be ground, the exhausts are pretty much throwaways. You seem to have a bit of an oiling problem on one cylinder, and a head leak on the left. Until they're cleaned and carefully inspected for cracks, these heads are a big question mark.

The Cap'n Thanks Cap`n How difficult is it to remove the heads without dropping the engine.Right now I have the head out as far as it can go. Its hits the wheel well and cant go any further.Can the head studs be removed to clear or do I have to drop the engine? |

Pull the engine, you'll spend less time doing the repair than trying to do it with the engine still in the car.

It like taking my first step a Little scarry but also an adventure.Serious Rich gave me an easy procedure for pulling it but I just did not have the time to do it. I was hoping that I could get the head off without pulling it.But I think Ineed to pull the other head to so I guess I will have to dive in. Thanks |

Thanks I really dived into the engine maintenance of my teener for the first time last summer. I agree that pulling the engine is a tad scary. However, it really is a lot easier than it first seems. Just remember, if you get into a bind, post your problems and pictures here. There are a ton of people out there that will provide expert advice. Eric |

Judging by your pictures, you have already put more work into this than it would take to remove the engine...

What a crappy design. I don't think the engine was designed to be dismantled while in the car. Dropping the engine is fairly simple, I like the furniture dolly method. You'll want to have it out to do a general cleanup. It's amazing how much crap can collect in the cylinder fins. Go for it. |

Tins are not designed to come off with the motor IN THE CAR. So, you drop the motor. Its really quite simple. Do you have a floor dolly? If you do, and two floor jacks, I will come over after work one of these nights. We can drop in in less than a hour...simple. rIch |

The problem with the motorcycle jack comes when you try to get the engine out from under the car after lowering it. You either need your jacks and jackstand to go higher or you have to remove the motor from the motorcycle jack and slide it on the floor. Remove your rear valance to give yourself more clearance.
I have seen McMark do this in about 30 minutes. I can do it in an hour or so but I am not trying to make a living at it. Just keep guys like McMark from making a living off of me (IMG:style_emoticons/default/blink.gif) |

You know what Rich told me this a while back. I will try to get a something better than a motorcycle jack. |

I highly suggest CHris Foley's engine plate, cost $120 delivered. This is to take the engine and tranny down as a unit. The engine plate is probably the best investment. I am on my second engnie drop in less than 1000 miles. front Galley plug(s). It took me more time to label things than the mechanics of dropping it. the first time it took me about 10 hours; the more recent one took me a few hours. I labeled less stuff.

While you are on it...
Get the shifter rod off. Remove the clutch cable and the speedo cable...bend gently towards the front of the car and under the car...no kinking. Pull the throttle cable down below and put it with the clutch cable. From there...30 minutes and two beers...we are done. Rich |
