Follow up: Dropped off my car with my local Ferrari technician yesterday, and he said that for expedience, he will weld up the pipe. He agreed that the pipe must be carefully checked when installed to ensure that it doesn't rub at either end. He said there are some tricks to getting it installed right. Sounds like you have it figured out Mark... |

I fixed my car last night, but I noticed that the duct was also rubbing on the fuel tank seam.
It seems the duct is located too low.
I pushed the duct up and drilled another hole (lower) in the tab on the duct. This way the duct does not rub on the fuel tank seam and it has less pressure on the coolant pipe. I took a picture if anybody wants to see it I will try to upload it.

Hans,
already looked, about $135. Meeting with Carlo this afternoon, we will discuss what he wants to do, weld or replace, I lean toward replace.... |

Check the Owner's site if you want to order a new one. They're not that bad. (At least they're reasonable on my car - not sure about the 328.) |

Mine never started leaking but it was darn close...it was touching the alternator pulley. I removed it, had it TIG welded (I think I paid $15) and all is well.
I also had one of the same type tubes....one of the ones going front to rear of the car....generate a pinhole leak due to its rubbing against the crossover pipe between the fuel tanks. I fixed that with a high dollar brand of JB weld type stuff and it has held for 6 years now.

That fiberglass air intake box was replaced with a tube in late 88.

Matt,
Could be a lot more work to fix. The air box inlet has created a flat spot on the pipe, and the subsequent pin hole. Not sure how you would build up that whole area....seems prudent to just get a new one, even if it costs a few hundred. I would prefer to have mechanic have one fabricated out of stainless steel, then sleeve the two vulnerable points with a peice of rubber hose. |

Verell,
I just completed the bandaid as you described; guess we were thinking alike (I used a peice of old hose). It took all of 20 minutes to complete. Only has to hold until Tuesday when I take it in. I will likely replace the pipe, but a slip of hose over the two vulnerable spots will be in order.

My '82 308 QV has rubber sleeves on the tube at each of the spots mentioned.
There are several ways to fix the leak. All involve draining the coolant down well below the leak. Then Clean the area with a good solvent (brake cleaner, lacquer thinner...) and a stainlee steel brush. Then:
1) fill with JB Weld.
2) Use a propane torch & welding rod for aluminum (it's actually a white metal solder) to repair the area. File/sand smooth afterwards.
3) Have a pro TIG weld the area.
Foor a bandaid, wrap a piece of ~1" wide rubber sheet around the area, trim the ends so that they just butt together, & hold it in place w/a pair of side-by-side hose clamps. |

Thomas, not to worry, I already had an appointment scheduled for this Tuesday. I am putting a "band-aid" on it to cover me till then. Car is getting a bunch of stuff tended to, so this will just get added to the list.
It does not look at all difficult to replace, BTW.
Would need to take the wheel off, fender liner and remove the air box related hardware. |

Mine went a couple of weeks ago. Not surprisingly they aren't cheap to replace. I had no warning, no sign of a little leak, I just walked out of the office one afternoon and saw the huge puddle of coolant under the car. A rubber gasket is cheap insurance.
David, I'm not sure how involved the fix is or if you could do it on your own, but I wouldn't wait to repair it.

Also, that same tube can/will rub against the gas tank. Just been there, done that. |

Sorry my digi-cam is broke. Easy to find. Look at the air box where the air filter is, then see the flexible rubber fitting? Now continue to the black fiberglass tube, now look directly under that....see the metal pipe with the 90 degree bend going straight down? That is the one, and about where that bend is, it will probably be touching the underside of that fiberglass tube. I would recommend wedging some 1cm thick rubber sheet in there to protect that metal pipe from wearing through. |

I found something similar on my 308 carb but in my case the hose was rubbing on the waterpump pully |

I found a problem with my car that may be common to all 328's. There is a coolant pipe on the right side of the engine compartment that runs from the top of the engine down and at the top, where there is a 90 degree bend, the pipe rubs on the air intake tube (fiberglass). This has worn a flat spot and subsequent pin-hole leak on this pipe. It now leaks quite good....for those that have not begun leaking, I would suggest you stick a peice of rubber mat or something to keep the two apart.
I think I recall a thread from a 308 QV owner that had this same problem |
