Thread: the disco backfired and blew off the pipes

In the photo .... where your second knuckle on your hand is .... you can see a T piece ... It suppose to join up there .... But you have got another large hose hooked up in it's place ( going over the Passenger rocker cover to somewhere)

At the T piece.....
1 large hose goes to a tin can on top of the drivers side rocker cover (rocker cover vent hose)
1 small hose goes to the plentium ... ( I can see the small hose in the photo)

That large hose that goes over the Passenger rocker cover ... Where's that going to???


I took the liberty of Posting up your photo .. Matt

That Long hose should connect there. as in these pics. If you have your hoses wrongly connected then it could run, but if you had the hoses blow off via a LPG back fire then your MAF could be stuffed.
$800, no you should get one for around $400 new on Ebay, There is a seller named Roverlord1 he has them.


The other end goes to the firetrap on the drivers side rocker cover

If you have LPG on that system and the PCV was still connected at that port (where your finger is pointing) then your LPG system was not installed correctly.

If you want to avoid problems with backfiring on LPG, then the PCV entry port into the air induction system has to be before the LPG mixer. (This is to avoid the problem of a flame igniting a fuel mixture outside the combustion chamber.)

You may also want to replace your flame trap on the RHS rocket cover.

Oops: should have looked closer, you do have LPG, the information and pictures in the posts by NotWorthComplaining in the case of an LPG system is incorrect. The LPG mixer ring is the thing connected to the tube near your left thumb, marked autogas. The PCV hose under your finger seems to be in the correct position, moved to before the mixer.

What you need to do is replace a blanking cap and put a hose clamp on it where your finger is pointing, and replace your flame trap.

ok that big hose that is suposed to hook onto that pipe where my finger is gose from
the driver side rockket cover to that T secetion from there it gose under the Air Flow Meter and plugs into that huge rubber pipe on the back between where the gas gose in and the Air Flow Meter is, not much of an air box left seen as it blows up so much some times 3 times in as little as 10 mins and stalls the car and i change it back to feul get it going again and change to gas again

show me some photos of this blanking cap and put a hose clamp on it where your finger is pointing, and replace flame trap

The pick I am showing is of an LPG installation, and it was fitted by LPG 1 in Victoria... they are reputed to be Land Rover LPG specialists, they don't use a mixer ring on the installation, they do it with the the Mixer unit bolted directly to the throttle body, so it may depend on installation of he system.

get it converted to gas injection, no backfires, no worries

If LPG 1 did the conversion and left the PCV port in that position then I wouldn't be going back there for another installation. It's wrong. You should be avoiding having a potential flame source inserted into a fuel/air mix. LPG 1 in Victoria was just being lazy.

Matt ... Your "wording" is hard to understand ... Reread It'sNotWorthComplaining! & Lotz-a-Landies posting's ....

A blanking cap looks like ... a 30mm long rubber hose with 1 end plugged off // Basically a plug

If your car starts and runs OK on petrol and gives no grief ... then your MAF is most probably OK ... Your backfiring is due to other items ... as your gas does not rely or use the MAF // MAF is for the Petrol side of things // MAF controls / signals the ECU for the fuel injectors

Whats your timing set at??

If it is backfiring all the time .... I would run it on only petrol .. and make haste to a gas mechanic
