Hatch/latch adjust? / Oil pressure reading at dash
This is my first post after buying a '79 928 (#0275) about 5 weeks ago. Got it for $3150 in very roadworthy condition - newer tires (although cheapies). It's a silver 5 speed with black leather. I guess the biggest "issues" will be having the front seat-bottoms re-worked for the typical loss of form, and it will need a repaint. Otherwise, the interior is complete - even the dash is well formed and nearly completely blemish free. The engine is a bit 'wet' with oil, but it doesn't seem to lose excessive amounts of oil. I'll probably be chasing that around for a while. First thing I gather is to inspect the crank vent system as the hose doesn't seem to be clamped at the block mounting plate. Altogether, I'm really happy with my 928 - it's meant to be fun ride, not a showpiece.
My first "stoopid 928 noob" questions is about the "alignment" of the rear hatch latch mechanism. When latched, my hatch is up/elevated about an extra 1/8" or so which makes the panel alignment look poor, as well as the extra wide panel gap along the bottom of the hatch. I'm familiar in other vehicles being able to set the receiver higher/lower to have the correct alignment when latched. Is there a way to accomplish this on the 928 that I've overlooked? Couldn't find it searching the forum or web... edit: I've shortened the two bumpers at the corners of the hatch and also lowered the bumper blocks mid-way down the sides of the hatch, but the hatch still sits a bit too high. I also see by the diagrams on Pelican Parts that there are 1 and 2 mm "Desk Pads" or spacers for the lower lock portion to create a larger gap. There are no such spacers installed in my car and the gap is still a bit too large... thus my question... Second, my dash indicator for oil pressure is nearly constantly pegged at '5.' At idle, it can come down to about 4, but otherwise it's maxxed. Is this normal? If not is sender or gauge the more likely culprit? I appreciate any help. I've been working on cars for over 20 years, so hopefully as my experience with the specifics of the 928 grow I can also give some back! Last edited by b1114p; 11-15-2008 at 02:19 PM..

Not sure about the hatch alignment problem. My '84 has a upper latch housing that is cracked, but still works. However, it doesn't let the hatch seat all the way. Check yours for this. Question #2, I'd try changing the sender down by the oil filter first. They are available at the usual parts shops, 928 International, etc. But also check that the two wires going to it are not reversed. One connector is bigger than the other, but mechanics have been known to force them on. If that doesn't help, you'll need to pull out the pod and clean all grounds and contacts on the instrument circuit board. Cleaning all ground connectors under the dash is also a very important thing for proper operation of accessories and gauges. Use a pencil eraser to clean the contacts on the fuse panel. Good luck and welcome to the Shark Tank!

I purchaced a '78 928 about two months ago, love this car. Mine also is a five speed but no sun roof. The no sun roof is one of the main reasons I bought this car along with the fact that it is a five speed. I had an issue with the volt meter reading 11 volts max. I thought I had a bad alternator until I put an external volt meter accross the battery. It turns out the problem was a bad ground at the fuse/relay panel. I learned of this thru this forum. There is one stud/bolt with about 5 or so brown ground wires, upper right side looking at the panel, that my son & I cleaned & now the volt meter works as it should. I think before digging into the dash, which is a real pain, try cleaning the ground wires. Just a thought, but an easy thing to do. From what I see on this forum, grounds are a major cause of things not working as they should. Here I thought Corvetts had ground issues. Hope this helps. By the way, this is a GREAT forum. Some one, some where always has an answer to a question.

congrats on joining the club.
![]() as others have commented on the hatch alignment, I will offer this on gauges: do not trust any 928 gauges as being accurate---928 electricals are a known problem. Your oil pressure pegged at 5 is typical, down to 4 when warm is no big deal. However---- one of your first projects should be to inspect and clean all electrical contacts. that means the negatives and the positives, front to back, side to side. Wally Plumley has a good write up on this (see 928 Specialist's website under tech/specs). He recommends this be done yearly. oil leaks are common, usually the oil pan gasket, which may be handled by tightening the oil pan bolts (be gentle). the steering rack is also subject to leaks as well with age. Your MY should be equipped with CIS K-Jet fuel injection (mechanical--not electric), and it is critical that the fuel system be kept clean. use a good grade/source of fuel, change the filter regularly, and if you let it sit (without running it) for an extended length of time, be sure to add Stabil to the gas tank or completely drain the system before storage (it's that time of the year for most folks up north...). CIS does not like to be mistreated in any way, and rebuilding the entire system is costly. take it slow, work on one thing at a time, and you will find it is a great car to enjoy. --Russ
