Today’s beautiful fall weather was perfect for rolling out the engine on its stand and power washing it. After the POR 15 degreaser and metal prep application, the engine was hosed off again and then left to dry in the sun. A few metal pieces were highlighted on the engine......

Spark plugs
Achieving better performance is a complex process of small incremental changes that all must work together in a sort of mechanical ecosystem; a higher grade component offset by a weaker one often proves fruitless. Spark (British say “sparking”) plugs may provide some gains. Original specification and alternatives The Jaguar Parts......
Making gaskets
With the front seal replaced,the timing chain cover plate is ready to be bolted back onto the engine block. However, the cover plate gasket is no longer available for the 2.4 engine; we ordered a 3.8 engine gasket anyway to see how thin the material needs to be. The photo......

These seals, once made out of asbestos, were notorious oil leakers, and Jaguar forums suggest a number of remedies, from machining the crankshaft......
Crankshaft front seal
Replacing the crankshaft front seal, housed between the oil pan and the front timing chain plate, is the most involved task of our planned engine restoration. The challenge is the multi-step process required to access the seal … once reached, actually replacing the seal itself is trivial. Damper hub After......
Inlet manifold removal, thermostat
The inlet manifold, an aluminum casting, communicates to the cylinder head through a series of passageways. Two carburetor mounts, with studs, are at the top. A separate water jacket connects to the main inlet manifold at four water ports. The water temperature sensor fits into a threaded hole in the......
Water pump removal
Our engine restoration plans include the replacement of the water pump located at the front of the engine block. We obtained a new unit from SNG Barratt. Once the bolts and stud nuts are removed, the water pump is easily pulled away from the timing chain cover at the front......
Oil filter upgrade
See also oil filter disassembly post. The torpedo-like canister that holds the oil filter carries the iconic look of the industrial age. Unfortunately, this design also makes changing oil a messy and unpleasant task. Modern spin-on filters are both easy to change and more effective in keeping the oil clean.......
Exhaust manifold: ceramic coating
See also exhaust manifold disassembly post. Apart from paint, there are three basic kinds of metal treatments used in our Mk2 restoration: ceramic coating powder coating cad plating (as well as tin-zinc DIY electroplating) We’ve selected Pro Finishing for ceramic and powder work (conveniently located next door to Classic Car......
