Yeh totally agree.  Bought mine direct from Dale thingy ? off of RX7club.com and they cured every problem I had with boost.  The first lot he sent got lost in the post, but he sent me a replacement set without question. Nice man.

So does anyone have any pictures for where you install them?

I\'m getting some for sure, And a diagram of where they fit would be very helpfull, nice pic would be good, and if someone could give a pic with the Knock senson is exactly,(think it may be in the same area) would be the cream!:)
Cheers Bob

I just bought some - getting him 2 send some more details (diagrams and pictures) to help everyone.

The knock sensor is on the passenger side of the block below (I think) the front spark plugs. It\'s a large hexagonal lump with a wire coming out of it.

Cheers,
Alex

Thanks Alex, still hoping for a pic,
But Bad news guys, Auction ended early, someone bought them all?? bugger! i\'m just leaving on hols now too!

That\'s all he sells on there. There will be some more on tonight 100% guaranteed. I have a vacume diagram, will post it later when i switch my other hdd on. I\'ve bought a set of these, but will only need 1 or 2. I took 4 solenoids out mine when removing the emissions crap out the car.

i did the same, i have both diagrams somewhere if i can find them ill post them but both are on this forum some where lads, and tbh if you cannot find the diagrams id stay out of the rats nest.

if you are going in there id re do ALL the pipes as well as they will all be on there last legs. it will keep you out of trouble for a good while, also get a mityvac vacuum and pressure pump and check all the solenoids. its not an easy job but worth it when your twins actually work as they are brilliant(just unreliable).

after the reduction of the rats nest its a lot easier to fault find as well.

+1 for sequential twins working properley. Just fantastic power from 1000rpm!

Iv had a set of dale clark viton check valves in my car for about 2 years now and i have to say they are fantastic and superb value for money as mazda will charge you £35 for just one valve.

Oh and in sure RX7guru on ebay is dale clarke so you will be getting them from a reliable person.
hes a seriously nice guy :)

Oh and this is his site, he used to sell the check valves from there.

This is what the guy emailed me:
 
I have plenty in stock and ready to ship. If other people on the forum are interested, here\'s the page to directly order them -

As far as where they go, here\'s the VERY handy vacuum diagram -

That shows the locations of the 4 check valves. The aluminum check valve is in the orange line in the diagram, and typically does not need to be replaced.
 
 
Also, if you need help removing the upper intake manifold, here\'s my writeup on how to do it -

So THIS is the thread! :)  I\'ve been wondering why check valve orders to the UK went through the roof this weekend!

I was really pleased to find a source for quality check valves for the FD about 2-3 years ago.  Mazda wants WAY too much for their check valves that are just going to fail on you again.  I still have the original engineering samples on my car - about 3 years and 40,000 miles on them, they look and work good as new.

I\'ve sold literally HUNDREDS of these, and I won\'t be done until every FD has them :).  

If you guys have any questions, please let me know.  I had to order another set from the factory this morning, so I have another batch of 100 check valves on the way, the new batch will be here Wednesday.

Thanks,
Dale

hehe welcome!! i bought some of these off your ebay sale around May - rapid delivery too thanks :)

Ah no, I appreciate it!  I\'m glad you guys found about about them - there\'s just not a lot you can put on an FD for $20 that works perfectly, lasts a long time, is better and cheaper than stock, and fixes problems.  It\'s one heckuva bargain :).

I also had to go pick up more mailing envelopes today :).  

While we\'re on the topic, I don\'t know if you guys have seen the Fighters Garage FD parts -

http://www.fighters-garage.com/rx7.html

I personally designed the AST and the intake.  Good price, good fit and finish, and works very well.  I\'m very good friends with the owner, Jimmy.  Just want to make sure you guys are aware of the good deals out there :).  It started when I installed a new Pettit AST for a friend - it looked terrible in the engine bay, fit was crap, and it was expensive.  Jimmy and I figured out how to make an AST that fits right, looks good, and works like it should.

Anyhow, enough rambling :).  Thanks you guys!

Dale
