Volkswagen Transporter syncro

1989 VW T25 Doka syncro (4wd) Spoiler. Engine trouble. 2.1 litre petrol. Rear locking differential. Pretty original condition. Really not much rust on the seams. Chassis is in very good nick. Power steering. Imported from Germany about 3 years ago. Lots of new parts fitted. Radiator. Oil pump. Air mass sensor. Brake shoes and calipers hoses. Reconditioned alternator. Various other bushes bits and bobs. Six seats, but only front driver and passenger have 3 points. Others lap belts. But I do have parts to fit two more 3 points belts, included with sale. Engine was replaced with a reconditioned unit from elite engines U.K. (last pic is when the new engine arrived June 2023 ) Comes with old engine. Was running nice, smooth and quiet. No problem cruising at 100kph, capable of more. D.O.E. till February 26 Unfortunately, there seems to be an issue with combustion pressure getting into the cooling system. Probably a head gasket. But I have ran out of money to throw at it. Not a bad investment for someone who can do the work. They can go for silly money.
