Question about 1994 Chevrolet Cavalier

1 Answer

Ran the engine way too hard

I have a 2.2 in my 94 Cavalier that is used for dirt oval track racing. Motor was said to have been rebuilt right before I bought the car, which seems to be the case as the motor has run flawlessly. Last time out I ran the car way too hard on a track bigger than what I should have been racing. The motor ran at way too high of RPMs at full throttle for about three laps in a row, at that point the RPMs started dropping and I thought the motor was cooked. I shut it down, the oil pressure still read 30# and the water temperature was about 220. Now, the engine will start but it runs rough and I can tell it is hurt. Where would you start of fixing this problem? What would be most likely to be the first parts to give out at sustained high RPMs? Is this a no-brainer that the engine will have to come out and be torn apart? Or, might I get lucky and find an easier fix such as valvetrain, etc?

Most of the time when this happends it has to do with valve train like broken valve spring, or bent valve , or even a bent push rod or colapes lifter, or rocker arm. At any rate i think your problem is in the valve train.

Hi back again I need to know why I would not get any compression in 1 3 5 7 or 6 can anyone tell me why cause I just rebuilt the motor a1976 Chevy 350 can you help

Hi Pete:
The very first things that I would check would be:
- the rocker arm/valve clearances. If they are too tight the valves cannot seat and you will get zero compression.
- Camshaft timing - Make sure that #1 piston is at TDC when you align the timing dots.
Great old motors! They were my favorites when racing dirt track stock cars in the 70's.
Hope to hear back from you.

Is a 97 2.4L GM motor capable of oval track racing performance. I've heard the oiling system and water pump can't handle it. Also been told that they work fine? What is what?

yes the 2.4 dual cam works well and fits great in most eco stock racing rules. I run one on a 3/8 mile high banked dirt track. The engines are light and so are the cavaliers. The waterpumps are not the easiest but i did not find it near as hard as everyone online cried about to change. Im not sure yet on the oil pump having a fualt to the bottom end issues, i lean more on the counter balance shafts airiating the oil at high rpms.

Hello I race a 1996 cavalier on a dirt track and I have been having some issues that don't seem to bad.the car will run fine for 4 laps depending on how much I get on it then it will just loose power I...

What kind of air box do you have? After racing in dirt for a few laps, is the air filter getting clogged up? I would say that or possibly intaking in hot engine air (cool air atomizes the fuel better). I'd start there... then move on to fuel issues.

I race a 1994 saturn on a dirt track. My car runs

Is it a stock engine?

If so check your ECTS water temperature SENSOR not sender, it's located on the right side of the block towards the bottom drivers side engine compartment.

Change the harness connector to it as well it usually goes bad due to corrosion, the original ects sensor was plastic which cracks, the replacement is 8 bucks at auto zone and is brass.

If this goes bad your engine will run rich, waste a lot of fuel and foul the plugs causing the engine to cut out.

If this is fine then check your ignition system for failures due to vibration.

I think its a dead cylinder

It sounds like you have a valve that may have dropped and is hitting the piston. It may be best if you remove the head and see what is going on. You may see the problem before you even get the head off.

You could also do a compression test to see if you have low compression on one or more cylinders.

Please post your progress
