Smoking 2000 Boxster S

[frankahola08]

My newly aquired Boxster S blows smoke when cornering hard to the left, otherwise it does not smoke at all. I have replaced the AOS and the car ran much better but I took a hard left today and it belched a cloud of smoke. The oil was just changed by previous owner, the oil gage in car is peged at full and the dipstick has oil above red plastic part. Will this happen if there is too much oil in crank case?

You have an overfill problem. Over fill will give similar symptoms to a bad AOS. You need to drain out about a half a quart. P car engines do not like to be overfilled so do this right away.

Thank you, this explains everything including the good price for the car!

Over fill happens all the time. A good Porsche tech know to put in 8 quarts then check the level and add what's needed. Some guys just dump all 9 quarts in (which creates an over-filled situation.)

I have heard some suggest on this board just to remove the oil filter housing which drains just about the right amount.

I once used a suction tool (through the dipstick tube) on my 996 to drain the excess. Very messy but it worked.

The oil filter housing sounds like the way to go....

Good luck and you shouldn't have any more problems once you get your level right..

Well after having my car apart this summer to do the IMS I discovered all kinds of blunders, wrong spark plugs, missing hose clamp on oil fill tube, two sets of injectors, the list goes on and on. :censored:

As to the smoking on hard left turns I had several vacuum leaks, 1) poorly installed spark plug tube on pasinger side, 2) no hose clamp on oil fill tube junction between motor tube and fire wall tube,

3) breather hose on oil cooler was just pushed on but at liest the hose clamp was on the tube just not in proper place, 4) and the iceing on the cake the oil return pump on the pasinger side was installed 180 degrees out. So hard left turn with a more than usual volume of air sucked through the AOS with the oil return pump pumping oil in the wrong direction = smoke screen!!!

So in previous posts I had a mystery piece in my oil pan that with help from this forum was determined to be a journal plug from within the head, the mismatched injectors were all on the passinger side, the wrongly installed oil pump was on the passinger side, sooo my guess the plug came from that side as well.

The thing that gets me is the car ran good,but now with many repairs and many parts the car runs incredible

Replaced parts- 2 radiators, water pump, low temp T-stat, spark plugs,spark plug HT leeds, spark plug tubes/seals, exhaust gaskets,intake gaskets, air pump system gaskets, oil breather tube O rings, IMS bearing, 6 flea bay injectors ultra sonicly cleaned flow tested w/seals, fuel filter, ultra sonicly cleaned fuel rail,

I only wish I had the cash to do my cluch, today I noticed cluch slippage on the 288 off ramp to 610 between third and fourth at 6,500 rpm, and for some reason my tires seem to be wearing rather quickly, cant imagin why :drive:

WoW frank, that smoke signal sent you down the road of discovery and fixes..

I have all the repair documents on my car from the PO, and I saw a receipt for a tune up.

Replaced 6 plugs and 5 coils. scratched my head wonder why not replace the 6th coil as well...?

Found a receipt 1 month later, same shop replaced 6 more plugs and the 6th coil. really 6 more plugs a month later..!

Thats why I have decided long ago to do my own work, I have seen work done by reputable shops that have left me scratching my head. I to have some of the PO's repair Docs and it had a complete tune up prior to my purchase and the work was done by a well reccomended shop here in Houston that shal remain nameless, so I did not think to check there work. Car Fax, PPI, and repair docs never tell the whole story when buying used cars it's just a role of the dice. I bought the car for a good price due to my negotiating skills and my doubt of all these things, eventhough all were positive. I often see complaints about maintanance costs on Porsche forum sites and my sugestion to those folks is sell the car and buy a mini van or some other form of white bread transportation. Sports cars are never an investment they are about the joy of driving, repairs, upkeep, and the cost of modifications are just the price of admissions. If these realities are too much for these folks I see a Kia in there future. :cheers:
