HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

need troubleshooting help from folks with BMW HB.

Post  murrayg on Fri Sep 19, 2014 9:15 pm

Hi all,

Ive got 2500 miles (in 6 weeks!) on my LS1 944 with Turn One pump, BMW HB, and power steering, with no problems. I am REALLY happy with the end result, steering and brakes feel just like back in the slow days. Today, the pump started to whine, actually quite bad. Everything still worked, just the pump was noisy. I checked the PS fluid with the car running and was surprised it see a huge volume of oil being returned to the reservoir (BMW one). It formed a nice "fountain" of oil, but remained within the reservoir. Can someone check to see if this is normal, with the engine running. Bad news is that I replaced the Turn One pump with a new GM one, and it too, whined. I'm at a loss as to what to do next. Any advice?

Gord.

I worked on those systems for years at dealers and various independent shops.
The problems we saw were mostly a hard pedal wich required replacing the accumulator, and the booster itself leaking. The only other part left is the DS regulator. I don't recall any problems
related to whiny pump but I supose it's possible that something in regulator is causing incorrect
flow to return side of resevoir. You may be able find a used one from a junkyard or ebay for not
too much money to swap out and eliminate it as a possibility.
Wish I could be of more help but it's been many years since I worked on one of those systems.
When I started my swap I heard of people using the BMW system, but recalling the
many failures I'd seen over the years made me opt for the Ford system. I'm going to build an
adapter to monut porsche master to ford booster. Hope this helps.

Over filled the pump? Have seen a lot of people overfill the pump and end up blowing them.

The pump has a remote reservoir, the BMW one. Not sure how you can over fill it. It's full to the point where it doesn't overflow when the bomb dumps with the engine off (pressing brakes when not running).
