Jenny, If you plan to keep that '87 Westy of yours I highly recommend
that you install a stainless steel system. The best scenario is to get the <A HREF="http://members.aol.com/Fkc43/stebro.htm">
STEBRO/Vanagon Stainless Steel Muffler & J-pipe.</A> Please click on the
highlighted link which will take you to our website where you will find
complete technical details, pictures of our muffler and j-pipe, pricing,
ordering instructions, and customer reviews. Our Muffler and J-pipe are
guaranteed for life. There is a 5% Vanagon List member discount which you
must ask for when placing your order.
For the header pipes I recommend you go with the DANSK stainless steel
ones that only <A HREF="http://www.busdepot.com/">The Bus Depot - Discount VW Parts - Main Menu</A> sells. These
DANSK made header pipes do not have the flanges or the support brackets made
from stainless, only the tubing is stainless. There is no warranty from
DANSK but the Bus Depot will give you a six month warranty. I have had a set
of these on my '87 Westy since June of 2000 when they first became available.
I have also installed many sets on my customer's Vanagons along with the
STEBRO/Vanagon Stainless Steel Muffler & J-pipe. This combination is
performing perfectly in all cases. I believe The Bus Depot will give you a
5% Vanagon List member discount which you must also ask for.
The CAT you can get through most local quality auto parts or from the
Bus Depot if you need it.
The cast iron collector piece can be had from the Bus Depot for a good
price.
The header studs/bolts that your mechanic is speaking of is a known
problem. Most always some if not all of them will break and require drilling
and tapping and sometimes helicoil insertion to get new treads back that will
hold your header securely to the heads without leaking. I recommend using
bolts in all locations instead of studs. I have in some instances enlarged
the threads in the head to take 1/2" bolts instead of the 14 mm that are
original. If you use the larger bolts you will need to enlarge the holes in
the header flanges and gaskets. In all cases make sure the holes in the
flanges are a bit larger than the bolts your using so there will be no
lateral stress on the flange. Use stainless steel bolts, flat washers and
lock washers with anti-sieze compound on the bolt threads. If the bolts
break at the front of the engine then they can be repaired without removing
the heads or engine. BUT, if the bolts break at the back of the engine then
the heads or engine will have to be removed to do the repair as there is
virtually no room there to work effectively.
This is now a good time to mention your possible head leak problem.
If it is found that the heads are leaking, which is VERY common, then it may
be best to remove the engine and have the head leak problem repaired and do
the header bolt repair at the same time. It would be best in this instance
to have helicoils inserted in all eight locations of the header flange
stud/bolts.
This would be a good time to make sure the cooling tins that cover the
push rod tubes are in good condition as they are attached to the header
flange bolts and it would not be economical to have to go under there again
to remove and install those header flange bolts again to get those cooling
tins replaced.
Good luck with your project and if I can be of any further assistance
please contact me.
Peace
Frank Condelli
