19 November 2020 - Engine out

8 January 2021 - All Drive Subaroo

Visited Narvi.

Range = 11-13,000

Present proposal.

Replace the two blocks. They are worn out and the water jacket is heavily deposited with some sort of yellow corrosion. Narvi thinks it was caused by a drop in the level of coolant in the radiator. The same deposit appears in the radiator and all the hoses. (Presumably also in the water pump.)

Replace the heads. Someone has worked on the heads and done a good job on the ports but has badly machines the valve seats. This has caused scoring on the valves. The after-market valves were damaged in the breakdown.

Replace the camshaft. The camshaft is an aftermarket high lift one. It is a very good quality one but not suitable for use with the fitted turbo or for the intended type of driving. This camshaft causes the boost to come in later, so there is no boost at the lower revs. Replacing the camshaft with a standard one will cause the boost to start earlier (at the expense of its effect running down earlier.

Replace the valves. The valves are not standard. About half the 16 valves were damaged in the breakdown and need to be replaced. As the heads and camshaft will be replaced with standard ones, the replacement valves can also be standard.

Keep the turbocharger. The turbo is from an STi. It has a larger capacity and will help in causing boost earlier.

Keep the crankshaft, conrods and piston heads. These are all good quality non-standard items and all in good condition.

Replace the sump. There are two dents in the sump which Narvi says mean it has to be replaced.

Replace the clutch.

Remove the oil catch can. The car did not originally have one and it does not need it. The one that has been used is a cheap generic one.

Some numbers on the engine block. But not the engine number itself.
