Z320 Posted September 8, 2023 Report Share Posted September 8, 2023 Hi there, another thread made me remind where the 4 cylinder TR engine can loose oil. Sadly all happened to me, I went through some deep and dark valleys since I own the car: - shaft of the repro petrol pump (simply caulked in position) drifted out of the housing - flank of oil pan punshed and gasket broken because of bolts fixed too tight - cork seal of the rocker cover shrinked and slipped under the cover - washer / nut holding the rocker cover not oil sealed - threads of both aluminum bridges going through in the engine and let oil out - at least the top thread of the timing cover goes through in the engine - both bolts of the ignition coil bracket too - all 3 bolts of the dynamo bracket too - push rod tube in the cylinder head not sealed pressed in the head - front crankshaft lip seal leather and not sealed - poor or missing valve stem seals - oil filter dripping Not cured until now: - no lip seal on the rear end of the crankshaft - any surprise No TR4A problem: - engine vented directly to the atmosphere on the left side of the engine I hope this listing can help a new TR owner.

Michel Higuet Posted September 9, 2023 Report Share Posted September 9, 2023 Indeed and especially for the inexperienced or the clumsy, for my part on my TR4A remains only... No lip seal on the rear end of the crankshaft Push rod tube in the cylinder head not sealed pressed in the head ( is there a solution for this one here ) Oil filter dripping? Are there still TR who don't have the spin-on adapter fixed on the adapter for the oil cooler? ( just joking... ). Quote Link to post Share on other sites
RogerH Posted September 9, 2023 Report Share Posted September 9, 2023 Hi Michael, the 'pressed in' fixing of the push rod tubes is the downfall of the leak situation. There is no sealant in there and capillary action takes over. You simply can't get the tubes tight enough into the head to stop capillary action taking place. It would be better if the tubes were slightly under sized and then sealed in with an RTV type sealant Roger Quote Link to post Share on other sites
Z320 Posted September 9, 2023 Author Report Share Posted September 9, 2023 (edited) Hi Michael, I solved the leaking tube this way in 2021, still sealed, no oil is creeping up from the lower end of the tubes. Good luck, doing it is not that much effort. Ciao, Marco Edited September 9, 2023 by Z320 Quote Link to post Share on other sites
