[Tigers] Dipstick and oil level report

[Larry Mayfield]

Ok, folks, you win. I think I will drop off of the list. I have been on it since the early 90s and have unfortunately seen the list degrade from something that actually meant something to car owners to this useless bandwidth wasting nonsense.

Ron,

First, thank you for the labor in doing this. For those who are strict and precise it seems like a chassis jig is your only hope! (LOL)

 

It would be interesting to know (not asking, just musing) what amount of the 4 quarts in the pan reduces due to pudding/clinking, oil passages and what does and doesn’t drain back from the filter. I am also curious, what, if any of the 4 quarts went outside the sump area. By that I mean did the oil height extend into the broader area of the pan. If it did then I’d estimate that volume increases 1-1/2 to 2 times once the oil reaches that point for a given dip stick rise amount.

 

I learned about the angle issue the hard way. I did an engine swap and to get the engine started dumped in (the only) 3 quarts of synthetic oil I had. The car started fine and I had good oil pressure idling. I shut it down and worked on other areas. Months later when the car was driven I would find that as the car warmed up - the oil pressure dropped. I checked the dip stick and making a mental compensation for the driveway angle felt the level was sufficient.  I mean, after all, I had put in 5 quarts (I thought) months ago.  It was only after seeking  exceptionally level ground and factoring for the significant 6-7 degree rearward angle of the engine (350 Chevy in a 64 Studebaker in case you are wondering) that in fact I was 2 full quarts low!  The good news is that no damage appeared to be done and in this case the repair was made with a funnel.

 

I still think that the best thing to do is an oil change (on level ground), warm the engine up, shut off and see where the dipstick level is after sitting a few minutes.  A file or Dremel tool can then be used to notch the stick. I then use the add/full range as a rough visual guide as it relates to the new mark.

I set up a fixture - 289 oil pan, timing cover and oil pump with pick up

 

I used my 260 Tiger dipstick and tube.    The end of this dipstick is about 1/2" off the bottom of the oil pan.

 

Leveled fixture front to back, side to side

 

2qt - level is at ADD line

3qt - level is 1/4" below FULL line

4qt - level is at the top L of FULL

 

Tiger oil lines hold about 4 oz

 

I calculated the volume for oil filters - actual fluid measurements probably vary

Fram PH8A = 49.214 cu in = 27.27 oz = 1.7 pt    ( 1.7 + .25 = 1.95 pt) almost 1qt

Fram PH3600 = 34.289 cu in = 18.99 oz = 1.18 pt

 

I measured the angle of my Tiger engine at 2 degrees tilted down at front

I measured the angle of my 1988 Mustang engine at 4 degrees tilted down at back

 

Tilt test

2 degree front        3qt - level is at FULL line

                            4qt - level is 1/16" below Ford logo oval

 

5 degree back    3qt - level is 1/4" above ADD line or just below mid line

                        4qt - level is 1/8" below FULL line

 

I never think the tilt of the engine would mean so much but there you have it - Tilt means everything with respect to the dipstick.
