I have a KE70 (Corolla 1980) which is leaking oil from sump. As per my mechanic the engine needs to be unmounted to replace the seal/packing as there is very low clearance b/w the crossmember and the sump. Is this correct?
I have had packings replaced and applied RTV silicone on newer model cars just by taking the sump off from below.
The packing costs harldy 100-150 rupees but it will be major work since engine needs to be taken off.
Experts are requested to please comment/advise.
