Head Bolts & Maintenance Issues:

This engine consists of two head bolts at the front of the engine that are shorter than the rest. The two shorter head bolts must be fitted in the corresponding holes at the front of the engine. Fitting the longer bolts in the shorter bolt holes will cause the head bolt to bottom out and the head gasket will not seal correctly. This will result in water and oil mixing, water entering the combustion chamber in cylinder one, and external oil/water leaks around the front of the engine.

These engines are also notorious for seizing camshafts as a result of poor maintenance and lack of oil changes. If you have an engine with a broken belt, be sure to check under the tappet cover for signs of oil sludge formation. If sludge build up is present, there’s a  good chance one or both of your camshafts have seized in the cylinder head.

Alternately, if your engine is still running ok but you know you’ve been a bit slack with servicing (doing more than 15,000kms without an oil change or using low-quality oils), its best to check under the tappet cover for signs of sludge. If you find signs of sludge build-up, you should talk to your local mechanic or give us a call as soon as possible to avoid costly engine damage.
