Moliver Posted January 23, 2022 Report Share Posted January 23, 2022 Hello All, I do have oil leaking in the front and aft area of the oil pan. For the front leak, I am quite confident, that the leak is around the two T-seals to the block. For the back area, I am still investigating. Although it is just a few drops, I am keen on geeting it dry. A conversion to the stiffer aluminum pan with a new seal would be one thought I have in mind (as cooling will be improved as well). Can the front-T seals be exchanged when taking off the pan as well ? Any input on futher commonly known leak spots on the TRs ? Input welcome! Cheers Oliver Quote Link to post Share on other sites
RogerH Posted January 23, 2022 Report Share Posted January 23, 2022 Hi Oliver, having a dry oil pan (sump) is what TR owners dream of. The front oil leak could also be from the timing chain case seal - this is a common area. The rear could be from the rocker cover (very common), the rear scroll seal (fit the Chris Marx lip seal) the camshaft core plug. The Aluminum oil pan may actually increase oil leaks as many are porous. Is the flange of you steel oil pan flat? Are the oil pan screws tight and sealed? To replace the T seals you would need to remove the front sealing block - I believe this is possible with the oil pan removed. Sweet dreams Roger Quote Link to post Share on other sites
Moliver Posted January 23, 2022 Author Report Share Posted January 23, 2022 Hi Roger, a good post reply always starts with the management of expectation, doesn't it ... Thanks for the input! Just for clarification: with "scroll seal" you mean the split rear crankshaft seal, corerect ? Cheers Oliver Quote Link to post Share on other sites
Moliver Posted January 23, 2022 Author Report Share Posted January 23, 2022 .. the leakage would then be through the cluth housing bottum hole (?) Quote Link to post Share on other sites

Yes and off the steel plate that closes the bell housing behind the oil pan/sump. My engine was dripping from here and it turned out to be the seal in the base of the oil filter bowl, under the long attachment bolt. New seal fitted at oil change solved that problem.

Cheers Oliver Front leaks could be the T shaped cork gasket or…….someone having put too long a bolt in and pushed through the aluminium block. Rear leak could be pan, could be rear crank seal, could be inadequate felt packing in the rear main bearing channel’s. Always worth checking when the pan is off that the bolt holes have the correct raised edges and that the pan is actually flat. Iain Quote Link to post Share on other sites
Teher Posted January 24, 2022 Report Share Posted January 24, 2022 Remember to check the felt seal of the oil dipstick ! Quote Link to post Share on other sites
Moliver Posted January 25, 2022 Author Report Share Posted January 25, 2022 Hi All, Thanks again. I think (despite the fact, that I have just completed an oil change) I will take the pan off and investigate. Ref Oil pan seal: Are there different quality standards available or just the straight forward cork one? Additional sealing compound recommended ?

Z320 Posted January 25, 2022 Report Share Posted January 25, 2022 (edited) Hi, another reason could be the push rod tubes leaking, I repaired that some weeks ago. The oil pan "bended" means the holes are "punched" by tightening the bolts too much; is a paper oil seal fitted you will find broken or squeezed. Please see my post on another forum how I pressed the holes / flange back: https://tr-freun.de/phpBB3/viewtopic.php?f=86&t=14523 Onother thing I've been told (never had this open) some of the threads at the front and rear go though in the crankcase. You never get this thread sealed with a steel washer, so I use fibre washers on the bolts in the middle. Anyway, a oily issue. This has not been built to be sealed the way we know this today.
