20 Most Recent 1991 Mitsubishi Mighty Max Questions & Answers


This is tricky Steve and aggravating to say the least.
Some thoughts:
  1. How good was the milling, grinding or machining of the cylinder head? Who really knows? Sometimes you get what you pay for.
  2. The cylinder head bolts require a very specific bolt down torque. Double check that.
  3. Was the gasket an OEM part or aftermarket? Makes a big diofference.
  4. Finally, is it really the head gasket joint that's leaking? Look closely. Maybe it's the coolant sensor tap that's leaking.
Hope this helps,
Good luck
Bud

It may depend on engine litre size. 4 cylinder shows top pulley for ac belt, needs to be loosened. to release tension.

6 cylinder shows tensioner pulley on mounting bracket for compressor. Loosen the bolt for tensioner pulley to release tension.

Did something seize up and break the belt? You might need to deal with a bigger problem before you just loosen up the tensioner bolt and put a new belt on. Loosen up the tensioner bolt, place the correct belt on, making sure you run it correctly around all the pulleys, then borrow (at OReillys or a similar) the long handled tool, you use to put tension back on the whole pulley system and tighten down the tension bolt. If it was me, I'd go to YouTube to look at a couple of DIY videos on the subject.

Sounds like tire separation. Don't drive with that tire on the truck. Put on the spare and have it checked by a tire shop. Good luck.

The problem may be a cam/crank position sensor that is causing this. Check that the cam shaft is turning ( broken timing belt/chain)

check ignition timing, exhaust system for blockages, fuel pressure ,injector tip condition, blocked air filter. Run the fault codes to check for faulty sensors.

When was it last fully serviced? Its 25 years old? You may need to invest in some TLC for your poor old Mitzi. Good to see its still alive though after 20 + years

if it's not on the sticker under the hood then look in a Chiltons manual for your truck.
