I recently took a 200 mile round trip in my TR4A. Oil consumption was around 1 qt per 100 miles (lots more than last year). Bottom of car is covered with oil from oil pan aft. There is oily film on deck lid and license plate. There is evidence of oil "spray" on garage floor, coming from exhaust pipes. Car starts and runs fine.
The PCV system vents from rocker arm cover thru a PCV valve and then to intake manifold. When running the engine, I observed the hose connected to the intake manifold to collapse (difficult to believe it could seal completely). I replaced the rubber diaphram inside the valve. The plunger and "valve" seemed to function ok. I restarted the engine and the hose again collapsed.
Should I just replace the hose with a stiffer version (existing one comes from Moss- I replaced all hoses 3 years ago) ? I believe oil comes out oil pan and rear seal, but I'm not sure how oil gets inside exhaust as compression is 150-160 on all cylinders.
Any advice appreciated.
