#1 OIL CAPCACITY OF 1971 S2, 4.2, 2+2

Post by MichaelDesna » Mon Jun 29, 2020 5:19 pm

Does anyone know the correct oil capacity of a 1971 Series 2, 4.2, 2 + 2 with the oil filter on ? Everything I read say 18 pints (9 US quarts), but my dipstick still reads at the "E" level and the car is on level ground in the garage.
Thanks,
Mike

Hi Mike....yes 8.5 lit(18 US pints).....a common problem with dipsticks is that when you push it into the sump is catches on the internal baffel and dosnt do straight down and get a true correct reading......you should have no curve in the stick and it should slide in easy going straight in......if you have kept on filling with oil it is now probably be overfilled...i would drain it...refill with the measured amount.....then note where this is on stick.....Steve

#3 Re: OIL FILTER LEAKING ON 1971 S2, 4.2, 2+2

Thanks, Steve. I'm going to check that dipstick tomorrow and make sure it's perfectly straight. I did put exactly 18 pints into the car when I changed the oil and filter so I now that the amount is correct. But when I recently tried to start the car after sitting for 6 years it started dripping oil where the oil filter apparatus screws into the "head". What do you think could be causing this ? I took the oil filter off and re-installed it and it still has a very slow drip (once every couple hours).

Hi Mike...probably the seal between the canister an the houseing.....there is a large ring seal that needs to be picked out and replaced....often in the box with the filter paper there are 2 seals.....you need to use the large one...also where the bolt goes through the canister there is a rubber seal..read through this tread.....it starts with spin on filter but then goes to standard type....Steve

"..you need to use the large one...also where the bolt goes through the canister there is a rubber seal..read through this tread...."

My car is different. I can only use the thinner of the two seals, the larger one will not go into the slot for the seal. I never get a leak from the canister to the filter head. Also my canister bolt is sealed with a felt washer, not a rubber one. To date I have never replaced it at service, and it has never leaked. Given that it is only a few pence I ought to replace it next time.

Thanks Steve and Chris:
I checked the dipstick and it is straight and goes all the way in to the stopper on the stick. It still reads just above the "E" on the bottom of the stick. So I drained all the oil and there was actually close to 10 quarts in there instead of the required 9 (18 pints). Would this have caused the oil to squirt out from somewhere when I tried to recently start it (but it wouldn't because the fuel pump is no good ----another issue) ?
Thanks,
Mike

The correct E-Type dipstick is precisely 10 inches from the collar to its tip. Any less (or more) and the dipstick reading will be wrong.

Hi Mike....too much oil could cause a problem the crankshaft can slap in to the oil and foam it up so lots of air in it then the oil pump cant pump the oily foam..or oil seals can start to leak more...is your dipstick the correct length...is your engine block from an xj6 they had a longer tube that the dipstick goes into so stick sits higher.....search dipstick...plenty of info on the forum....Steve

Thank you, guys. I'm out of town taking care of my Mom after having surgery but when I get home I will check out that dipstick. I only cranked the engine for a few seconds so I hope I don't have the issues you described, Steve. There is a new fuel pump from SNG waiting for me at home so when I get home in hopefully a couple days I'll install it and try starting it again. Cheers !

Sounds like a contender given what you're finding. I believe the XJ6 block was smooth compared to fluted? Or vice versa? So should be easy to check if so.. Maybe the start point as Steve says is to measure the length of your dipstick..
