Thanks, guys I will go with the T4. Are there any videos out there to check to fix the likely leak near the bell housing? I guess once it's opened I will need a new gasket as well. Any links to buy that?

I replace 1 quart of oil with 1 quart of Lucas Stabilizer for high mileage engines. Purrs like a kitten. But warning--I live where it is warm, so adding Lucas to your engine in NY winters may not be the best option.

After you do an oil change, wipe the bottom of the car with a degreaser. Let the engine run and use a small camera to see where the oil drips from. Diagnose. Diagnose. Diagnose. Before you start fixing anything. Many people on this forum spend fortunes fixes issues that never were ;-)

 

1) Oil Leak on my 04 Disco: 3 yrs ago, I had all gaskets replaced because of a minor leak. Last oil change, I switched from regular Interval synth blend oil changes at Firestone to Mobile1 full synthetic (only once). Now with another 1,500 miles I have leaks. I felt its structural thinness seeped through hence the leak(s).

I drive it less than 2,500 miles/year in the San Fernando Valley area of Los Angeles (hot summers with temps into the 90s and 100s). I own it since 2010 (then 45k mes) now at 85k orig. miles.

I read much about the subject of synth v blend v conventional. Before this thread I did not know about the Shell brand that most everyone here is touting. I’m thinking on reverting to full dino 10w40. Looking on Walmart at Castrol GTX, Pennzoil and Pennzoil High Mileage.

History: it went to a body shop Collision Body Specialists for paint not an accident 2 yrs ago. That was a veritable nightmarish experience where they painted the whole v without my prior approval. It came out with several issues.

2) The 3 sisters have started to come on and off intermittently. Not much to do from what I read about this - basically when 3sis engaged > no ABS.

3) The break light Is now on. Likely a break oil leak from front right and/or its caliper.

I love my 04 Disco but hate leaks. Perhaps in a year I should change the entire engine to something else and if so what and where to get that done at. I don’t know!

Appreciate collective thoughts on all 3 matters from the seasoned and the experienced with my thanks in advance.
