ok so i picked up a 1980 porsche 928 with about 219k on it the problems im faced with is theres loud ticking in the engine bay the slave cylinder is leaking so im assuming that needs to be replaced however the clutch is starting to grind while attempting to put in gear and the thermostat needs to be replaced any suggestions as to where i should start?

An oil change and some Rislone might help free up a sticking lifter which may be the ticking noise.

A new thermostat is relatively painless

Slave cylinder should be done and may be contributing to the grinding when you are putting it in gear. Try fixing that and see what happens to the grinding. The clutch may not be fully disengaging and causing the gears to grind, but it would probably be in all gears. If its only on 2nd and 3rd and not in 5th, then see the next line.

If the grinding remains, you likely need new syncros - not especially good news, work and cost wise.

Good luck.

219K and it's just starting to get broken in good!!

Why do you believe you need to replace the thermostat? Besides the obvious engine overheating symptoms, are there other symptoms?

Replacing the slave cylinder may cure most of your grinding. Just make sure you bleed it very well.

The loud ticking you hear could be the injectors firing. I was surprised how loud they were the first times I heard them. If you determine that it is a stuck lifter, the Rislone or B-12 Chemtool may free it up.

Good Luck!

thanks a ton i just ordered the parts and am anxiously waiting for them to do the work when i had the clutch pedal completly to the floor it didnt matter which gear i was trying to go into it was grinding so i didnt really want to force it in for fear of breaking something and also a couple times i started it up and really revved it and noticed some gray smoke coming out the back is it just because of the age of the car and from sitting? it doesnt sound like there is an exhaust leak at all so im not sure what that could be as well

You have no clue as to what you're in for do you?

OK well you hopefully proved that your slave cylinder is completely fuba. this explains the grinding in all gears. Replace the slave then read all the various posts about bleeding the clutch system - you will not get it bled properly if you don't read them, understand, and put into effect.

Re overheating - could be the stat - change it is cheap - but be aware that the 928 engine has a stat that doesn't just open like a normal car it also closes another passage for water when it gets to the roght temperature - ie if you have no stat fitted it will overheat.

Ticking noise is valve lifters most probably. Once the clutch is fixed and the overheating problem also change the oil and filter then give it an italian tune up - that will likely fix it.

Who is "them" and have they given you any estimates on how much $$$ they aer going to rape you, err I mean charge you for your 1st Porsche project?

Most ppl here are DIY due to the following facts:
A) 99% of all shops, Porsche shops included, don't know 928s.
B) Shop labor = $$$$$$$$$$$$$$$$
C) Wrenching on a finely engineered classic exotic supercar is fun!


Good, don't break stuff. It's expensive.


Hard to tell. Could be be from sitting, could be impending doom. Only driving it will tell. Fix the clutch first.

Your best friend at this point is the Search Function of this forum. Use it BEFORE you ask questions.

Oh, and Layton - don't take this the wrong way but PLEASE use some sort of punctuation and seperate your seperate thoughts - your ADHD-style-newbie run-on sentences are difficult to read. Slow down, organize, stay focused.

A decent general plan:
1) get all routine maintenance up to date: fluids, hoses, brakes, belts, tires, everything. This is a tall order for an old neglected 928.
2) fix driveability issues (thermostat, clutch or tranny, smoking motor, etc)
3) fix annoying issues (928s always have interesting electrical glitches)
4) fix cosmetic issues (interior, exterior)
5) now you may be broke and in debt, as well as seriously addicted to 928s.
6) if you're not broke, begin performance upgrades...








Neither did I...

i ordered the parts from performanceproducts.com they specialize in porsche parts, sorry about the grammar as well. Is there any brand of oil or oil filter one would recommend over the other? as well as spark plugs? The only other electrical glitch with the car is the tach doesn't work i can rev the engine but the needle stays where its at on the gauge.

Since you do not do your own wrenching, I would sell the car ASAP as you are just scratching the surface problem-wise/money-wise. Unless of course you enjoy these types of projects.

Jim bailey - 928 International

You might want to click into the store below my name since we ONLY do 928 parts !! Order a free 50 page catalogue of just 928 parts. We inventory far more 928 parts than ANYONE including good used parts from over 600 or so 928s that we have dismantled. The primary reason that you can buy an old 928 for very little is that repair bills if you pay someone else to do it can quickly exceed what you paid for it. Project 928s can be a great HOBBY if you enjoy working on it and do not mind if it takes you a few weekends or more to fix an issue. I have in the past when in the GRINCH mode told people that they were about $10,000 away from having a $5,000 car... The LAST 928s were $100,000 plus cars when new BUT when you are buying replacement parts you STILL pay as though the car were still $100,000. A Porsche shop could be working on a new $100,000 plus 911 GT3 or your 1980 928 so labor charges are also based on a high value, expensive car. Having a shop which knows NOTHING about a 928 does not have the workshop manuals or a belt tension tool is usually more costly than the "expensive" Porsche shop. That said , I am quite willing to provide you with any parts that you need as well as guidance and encouragement should you wish to fix some of the things yourself.

What Jim said. I think you will find 928 Int'l and/or 928 Specialists are cheaper (note: I didn't say cheap) and definitely more knowledgable than other suppliers. Having said that, there are: Parts Heaven in LA and there is a salvage shop in Houston that has 928s, but they generally cannot advise you on the procedures.

Do not take it to the dealer in the burbs up there.....I made that terrible choice with my first 928 when I lived in WNY a few years back. If you don't wrench yourself, there is a good place just off South Park, in Lackawana(?) or thereabouts....

Good Luck!!!!!!!

Read your manual, too.

Here are a couple of things to add to the list here.

-Check your upper radiator hose where it is close to your p/s pulley. If it's not tied back, check for a vertical wear groove. If you don't find one, good, just tie it back toward the radiator with a tie-wrap.

-Check to make sure you have both C-clamps on the L-side of your headlight bar assmbly - don't know what the part is called, but it is the vertical piece that rotates the headlight bar. Making sure those clamps are there is a good thing to do on a regular basis.

Always carry extra fuses, roll of electrical tape and philips srewdriver. It is also a good idea to put your workshop manuals on a thumbdrive and keep it with the car for help during emergencies.

Somewhere Heinrich has posted a fairly detailed list of the "small things" to begin with. I can't find it through searching or in my own bookmarks - maybe someone else knows where it is????? If I remember correctly, the list was in response to someone considering a supercharger.

You could use the "small stuff" list to do all those little 20-30 minute jobs that are so vital to the health of your shark.
