I am a new 914/6 owner and I finally spent the weekend driving the car. One thing I have noticed is the sound of oil entering the oil tank. It is a bit un nerving as it periodic. Basically it sounds like oil pouring from the top of the tank down to the bottom. It is a function of engine speed. Could there be anything wrong with the oil tank plumbing? I have not examined the oil system too closely. The car has the original oil tank but the car also has a 914/6 GT front mounted oil cooler. I have never driven another 914/6 but would not be too suspicious except that the previous owner included another factory 914/6 oil tank in the deal.

If anyone else has this same sound I would feel better.

Hey Evan. Welcome to the club

All the sixes make the gurgling noise you are making reference too. I have seen (recently) a 9146 tank that was hooked up backwards in a race car that has been ran for over a year straight without any issues. It scared me when I noticed (HOLY SH_T is what I said) but it seems to be fine hooked up backwards. In a stock 9146 it is nearly impossible to hook it up backwards. Somebody would have to go WAY out of their way to do it.

Thanks Brad

Confirmation of similar sounds from others' is all I needed.

Evan,

what color is your car ?? who does the service work on it ?? I lived in Novato for 2 years...



B

yes - it's normal.
you might try changing filters to see if it helps - sometimes it does, a little.
use only an approved, high-quality filter -- Mann, Knecht, Purolator - there are a couple of others that are okay but for sure these will work. all the reputable sources have them. FLAPS usually don't. avoid FRAM...

Mine gurgles...

Welcome

Hey Evan,
I'd be interested in the other 914-6 oil tank.

didn't even read that part

I'm closer to him... :finger2:


B

Thanks for all the information.

The car is red. I got it from a guy named Steve Young in Atherton. The car was originally irish green. I do not know much about the car. It was painted red quite a while ago. It has steel GT flares and a front mounted oil cooler. It has a 3.2 and a later side shifter. The rear trailing arm mounting points have been reinforced with tubing and gussets that are definately different than the kits that are for sale. It came with a very nice bolt in roll cage and a 914/6 GT driver's seat. It has aluminum S brakes up front on adjustable Konis. It has 15x7 and 15x8 Fuchs (with new 285/40 P7s). I think the previous owner had the car repainted and installed the the 3.2. He said the previous engine was a 2.4. He did say it was a bay area car that was used as an autocrosser the PCA member PO. If anyone knows any history of the car I would appreciate any info.

Regarding the oil tank. The one on the car has a lot of overspray and I planned on switching them out. The other looks very original and unmolested. After I do the switchout I will probably make the other available as I have only one car.

Thanks again,

Evan

Sounds like a cool car. Congrats on the purchase.

The later engines (3.0 and up) really move a LOT of oil... the noise you hear isnt bad in a stockish 2.0/2.2/2.4 engine'd 9146.


B

seriously, I coud really use one of the tanks. Overspray doesn't bother me

I like overspray.

I'll pay $1.00 more than Sean... beats waiting for "someone" to get a carbon fiber replica

But hey... if we keep this price banter up Evan's gonna get the impression these things are worth more than $75.00

Huh?

Mine sounds like my stomach after Thanksgiving Day dinner I can only hear it at startup... after I start driving, I can't hear anything but the engine (it's a good thing )

Mann.

JP,

I have found the 3.0 and 3.2 cars make more oil gurgling noises than the earlier engines... I didnt test with a sound meter...

I attribute the more noise with a higher volume pump..

Check Anderson's book (pg 63) for more info & report back

Still should be accurate. The pump ratio changed in 76 so B-hole is correct with his 2.0/2.2/2.4 thingy but he should have stated "2.7 and up".

Sorry.. the 2.7's dont exist in my world..LOL :finger2: I live in the "spirit world" say it real slow like your drunk... "I'm in the spirit world".. movie reference.



B

Yeah those 73 Carerra RS's really sucked...

...to say nothing of the 916's ...

Ayup, changed in the 76, 2.7 L. the scavenge side of the pump (which feeds the oil tank) was made *smaller* and the pressure side made larger.

Maybe it's a sucking sound

Told ya... they sucked!

I can't believe you guys can hear an oil sound. I can't hear anything but engine when I am driving mine.
