I recently bought a 1986 NA MR2, and I'm having issues with the engine:
- A loud 'knocking' noise (can be described as ticking, because the sound is persistent) at around 2000rpm in First and Second, just after 3000rpm in Third and Fourth, and just after 4000 in Fifth. I brought the car to a mechanic and he said that it could be the piston connecting rods, but he doesn't know for sure. It sounded deep inside the engine, and you can only hear the sound when accelerating.
- Leaks oil, from the block somewhere, and there is also oil in the valve cover over the 1 and 2 cylinder spark plugs.
I'm on a tight budget and I was wondering if it would be cheaper to fix these problems, or if I should just swap in a new engine.
And, if you could provide some kind of knowledge towards this 'knocking' sound?
Thanks
