Author Message   Conor Furr Posted on Saturday, September 07, 2002 - 06:41 pm:    This might be a stupid question but can you change the oil filter with out changing the oil. i ended up having to have some one else change my oil for me, and they put a Fram oil filter on, and id like to change it back to a mobil one filter. thanks. Conor   Leslie N. Bright (Leslie) Posted on Saturday, September 07, 2002 - 08:20 pm:    Get your Mobil filter, fill it with oil, take off the Fram and put the Mobil on. Start it for a bit, then check your oil level, adjust if necessary. You don't have to drain the oil. AAMOF, you should drain and replace the oil before changing the filter on a Disco, to prevent to oil pump from losing its prime. FWIW... -L   Conor Furr Posted on Saturday, September 07, 2002 - 08:52 pm:    Thanks for the help, just had the oil changed today, and i dont really want to pay for another 7 qts of oil. ill try it out and hopefully i wont run into any problems. Conor   hendrik Posted on Sunday, September 08, 2002 - 06:45 am:    Leslie answered your question. BTW. LR says you must not drain engine oil AND remove the oil filter simultaneously. That might let the oil pump become dry and on restart it could not build up oil pressure. I´ve heard of new engines (GM make) becoming replaced few times because just filter was put on and oil filled in but the pump not primed until sombdy remembered. Has anyone had these problems with the Rover engines ?. I dare not to try it and every time I put off and on a filter, start engine until the light goes off and then replace engine oil.   Javier Velador (Jvelador) Posted on Tuesday, September 10, 2002 - 03:32 am:    I doubt most Jiffy Lubes know this. But I could be wrong. I just replaced mine and did not know about the pump/filter thing. So far, it has not cause a problem [knocking on wood]. Next time, I'll definitely follow the procedure. Javier   muskyman Posted on Tuesday, September 10, 2002 - 07:33 am:    its only a problem if you take a long time to do the oil change the film strength of the old oil will hold enough in the pump to hold the prime lube change places take only a minute or 2 with the oil out so they dont worry about it but the people that drop the filter then drain the pan then go to lunch...they can have problems   Bill Bettridge (Billb) Posted on Tuesday, September 10, 2002 - 09:07 am:    I don't know how that same rumour keeps getting recycled! It seems to pop up here every so often....remember, there is no magic on the Rover 3.9 or 4.0 - it's JUST a small block V8. Change your damn oil anyway you want to! Like Musky said, unless you let it sit for a day MIGHT have an issue, but otherwise, just don't worry about it. Geez - OK enough of my rant..... Bill   Paul T. Schram (Paulschram) Posted on Tuesday, September 10, 2002 - 10:30 am:    Bill: I agree with you wholeheartedly. Being a worrying type and very anal about many things, I was worried too, however, as many on the board know, I change my oil VERY often... When changing my oil, I almost always pull the oil filter while the pan is draining, then, I go to get the oil and fill the filter while the rest is draining. I might even stop for a beer in mid job! So far, no problems with oil pump prime. I would like to hear a real story of someone who actually had to reprime a pump after an oil change. I suspect that this might be a down in Sussex story (somehow, referring to it as a "down in Tennessee" story didn't quite fit). Oh, last comment-once you get the heads off, they are all small block chevys! Paul   Ariel Amoranto Posted on Tuesday, September 10, 2002 - 12:53 pm:    Is it 6 quarts or 7 quarts of oil on every oil change? In the manual it said 6.something quart on a dry.   Paul T. Schram (Paulschram) Posted on Tuesday, September 10, 2002 - 02:17 pm:    Ariel, Some of the confusion over the ullage of these engines and fuel tanks is probably due to the manual referencing imperial units, rather than US, consequently, it might take more US quarts than imperial. I buy my oil in bulk and just fill it 'til the level is reached! If it's your first oil change on the Disco, buy seven quarts and make a note for next time! Paul   hendrik Posted on Tuesday, September 10, 2002 - 02:36 pm:    Ok, then I can relax. I´ve just been cyting the workshop manual and if I take a risk I try to figure out before, whether I want to "pay the price" - in this case decided to be on the safe side. The draining thing makes sense. It was a new and certainly not "pre-primed" oil pump in that new engine I mentioned. The 4.zyl Engines just don´t need pre-priming, the V8 does before the first start (or the petroleum jelly stuff I think). Point is, small block chevys are (and were) the minority in Germany. Opel (through connection with GM) introduced one about 25 years ago. But mainly we were given in-line 4s or 6es. No wonder experience is scarce - to my excuse gives reason to be a bit embarrassed if you hear you were overcautios and recommend others to be so too ;) .
