Acquired car in used condition. Started giving it a general tune up. Realized the rear intake gasket was blown. Bought a gasket kit but I don't want to replace the gaskets if it won't fix the problem. The front control arm was not attached and in the back, where the gasket went bad, the flap is bent. Would one or both of these situations cause the gasket to blow? I've already straightened the flap. Is it likely that replacing the gaskets will be worth my time? Or is it likely that this has led to more serious engine problems?

Hard telling what made the gasket blow but with the mileage just age and mileage could have. If the flap is/was bent and you fixed it then it should be ok. I'd be more concerned about the control arm not being attached. Was it in a wreck? Or worse yet rust? But in the same token the control arm may have done the problem due to a gauge is supposed to be used when installing it on the driver side.

The car was free from a family member. It sat for about 2 years, after they were told that it needed a really thorough tune up. It was not in a wreck. There is hardly any rust on or in the car. I am looking to get it running to save gas commuting to work. I have checked all of the spark plugs, vacuumed out the mice nests under the hood, performed a spark test, and diagnosed an intake leak. I did a compression test before I found the bent flap. I have been working with a family member who is a mechanic. However, due to the fact that this engine sits sideways and neither of us have dealt with that before, we are at a stand still. He told me that without compression, the problem could be a lifter or a hole in the piston. That was before he knew about the bent flap. The car starts and has driven down the road. It backfired because of the vacuum leaks. Now I have the top side of the motor apart, down to the intake gaskets. Do you think this car would likely run with changed gaskets and reattaching the control arm? I have found the square clips that the control arm goes in to. The clip was missing when I got the car.

I don't hve a good pic of the bent flap that you are talking about if the car ran it has compression someplace. Check the numbers and send them back a 20% variance or above means something is wrong with one of the cylinders. The intake gasket should put it in decent order. If your check engine light is on auto parts can scan for free. Also check fuel pressure with a gauge auto parts rent it. Not seeing the car makes it hard to tell you one way or another but I thin k you'll be ok. Just make sure to get a front end alignment after fixing control arm and see if motor mount is connected because that supposed ly has to come out to fix your control arm.

I think I did not communicate it correctly. I was talking about the throttle control arms that control the flaps on the intake. If this changes any of your advice, please let me know. Otherwise, I will check the things you suggested. Thank you for your time and information! It is greatly appreciated.

Just make sure nothing binds if it's for the throttle plates. Make sure everything is free and very easy to operate.
