Head Gasket Repair Log
July 8, 2002:  

*** READ THIS ***

Ok.  We're back home after nearly 3 weeks away, and it's time to finish reassembling this guy and see if he runs.  I'll be putting the finishing touches on this section of my site over the next several days.  Today, we have a heat index of 108, and I'm not going to do anything until maybe this evening, so please be patient.

Meanwhile, you can browse the pages below and catch up on what has transpired to date.

May 27, 2002 Day 1: One Step Forward; Two Backwards

In the grand tradition that is implied by the title of this section, I began the day by putting the VW on the ramps on the driveway. I decided to work there after all... I'll be closer to my tools and won't be as messy during the rains we're expecting this week.

I began by warming up the engine to prepare for the compression tests. I noticed a steady drip... almost a stream of coolant coming from the passenger side head. Also, when the exhaust pipes became heated, a lot of smoke came off the cross pipe. I couldn't see any coolant dripping on it, and it didn't appear to have any holes in it, so I don't know what this is. After a while, it dissipated. I see a lot of oil on the bottom of the front of the engine where it bolts onto the transmission. hmmm...

After warming up the engine, I attempted to remove plugs 3 and 4 on the driver's side. Those plug wires are really on! Had to use pliers to get them loosened enough that I could pull them off. They have big metal sleeves that fit entirely over the top of the plug. While working on the wire on plug #3, I snapped a totally worn out piece of coolant hose (small diameter) running from the top of the coolant reservoir to a big cross pipe. That started a steady stream of coolant dripping onto the top of the engine. Jean had a piece of hose in the garage that she was using for her pond pumps that I was able to snug around the fitting with a hose clamp. I stuck the other end into an empty gallon jug. By that time, it had stopped dripping.


I went back to work on plug wire #3 and finally got it off. I can't see where those metal sleeves hook into anything... Seems to just be a friction fit, but man was it tough to get off! I did though, finally, and got the spark plug socket out of my superdeluxe metric/english socket and wrench set, only to discover that the 5/8" socket doesn't fit anything! It's even too small for the plug on my rototiller! What good is it, anyway?

So now I wait till tomorrow when I can get a replacement hose for the cooling system and a socket that will fit those Bosch spark plugs. I have my Bentley, and I'm about to try to determine what size I need. Phooey!

Here's a photo of the broken coolant hose:


May 28, 2002, Day 2:  We Spend Some Money and We Try Again

Went to the local NAPA store to find replacement coolant hose.  No dice.  Didn't even have it in their catalog.  Picked up a 13/16 spark plug socket for $6 and change.  Checked out their metric calipers.  Cheapest one was $36.  I'll pass.  Time to work on my metric conversions.   Drove to the local Porsche shop.  What luck.  He just happened to have a 2 foot length of the hose I needed.  Sold it to me for $10.  Not bad.  Bus Depot lists this replacement for $6.95 (I think).  I'll have enough for this and the piece between the expansion tank and the overflow/fill tank.   The coolant hose went onto the near nipple with no problem.  I had to use vaseline to get it to go onto the far one near the firewall.  But it's on, and seems solid enough.

I warmed up the engine again, and was able to pull the plugs and install my compression gauge.  With the help of my wife who was running the ignition switch and pushing the accelerator, I recorded the following data:

Passenger side head (this is the one that leaks) -- #1 - 150 psi;  #2  150 psi
Driver's side -- #3 - 160 psi; #4 - 165 psi

Bentley says the nominal value should be between 145 and 189 psi, so I think I'm ok.  

Plugs looked good, too (see photos below).  Tomorrow, I drain fluids and yank that head clean off!




Continue to Day 3...
