Re: Oil in the air intake tube

Here's my results on the snap test.

Idle-20 inHG
2000 rpm-20 inHg
Snapped-22.5 inHg

Snap velocity rise was good, no hesitation, and no wandering or erratic kneedle movement throughout the test. Only noticeble thing was the hesitation of the kneedle before it dropped back to 20 inHG....

Re: Oil in the air intake tube

At idle I tapped(slapped)the throttle barely, so the vaccum dropped no more than 4 HG. Then it only rose to 20 HG before settling to 19 HG.

Re: Oil in the air intake tube

My vac reading at idle lye's within the normal marked green range. The reading is 19. Not sure of the unit measurement but I believe it's inH20. I did the vac snap test. I'm still waiting to do a compression test.

Re: Oil in the air intake tube

It's a nice puddle. I'm loosing a quart every 3000. After doing the vac test again, I did the snap test. The pressure only snapped back up to 20, so, I agree it's probably early stage piston ring wear

MAF burn off wire test/86' 740

Exactly what does the volt meter do to deflect for 1 sec after shutting the motor off after 4 SEC's? What values am I looking for?

Re: Smoke testing needed

Naw, I already tried it. Not working out for me. I found a mechanic with a history on 740's and he does smoke testing, so, while at it, I can get his expertise locking down the lock ring. Ever since I took out the sending unit in 2015, I have nothing but trouble passing EVAP.

Smoke testing needed

Due to EVAP problems. Not sure about using smog shop. Not interested in the BAR $500 voucher. I know my car and I need a smoke test, not hidden cost(s) for testing and repairs.

86' 740 gas filler hose

Looking for a new gas filler hose. Mine is the smooth one. Not the one with groove and ridge's. The 86' is a bit shorter also. EVAP continues to fail and my gas tank will not pressurise with "whoosh" upon cap removal, ever since I removed the sending unit in 2015. I've already changed the sending ga...
