Ok .... I am finally about to order the parts to fix my car. I am planing on changing the PD and sending the injectors to get cleaned. I have a Haynes manual on the way too.

I am about to order the parts from Mazdatrix.

Now for my question .....

Do I need all 4 of the gaskets listed below?

Manifold To Engine gasket - Part# 13-111A-N326

Manifold Water "O" Rings - Part# 13-1130-8527

Between Upper and Lower Manifolds (injection) - Part# 13-112A-N326

Upper Manifold to Plenum - 13-135A-N326

You can see all these parts at this link ... http://www.mazdatrix.com/c-2.htm

Thanks

George

Assuming that your car is an 87 N/A,and that all you intend to do is get at the fuel rails for the PD and fuel injector removal,you may only need one gasket,p/n N326-13-112A.You take the upper manifold and plenum off as one piece.In many cases it is possible to re use that gasket depending on how it comes off.But for $8 it is better to have it available.What you really will need are the fuel injector insulators,4x N326-13-257,grommets,4x8457-13-252 and o-rings,4x8574-13-253.Sometimes shops which clean your injectors will supply these but in my experience factory parts are better.

The manifold o-rings you mentioned are for turbo engines.

 

Thanks

Now I can order the parts I need!

I new about the Injector O rings, insulators and gormetts ... just wasn't sure about the intake gaskets ... Also I'm gonna get some new fuel injector hose

 

Make sure you get very good quality high pressure fuel hose or you will be doing the job again very soon!

 

Where is a good place to get the high pressure fuel hose at?

 

I have always used factory parts.

 

Make sure you get high pressure fuel hose. There is a difference and if you don't ask for it they'll just give you regular hose. Gary
