Question about 1987 Plymouth Caravelle

2 Answers

'87 Plymouth Caravelle vacuum hoses crumbled.

When I tried to replace the PCV valve on my 2.5, 4-banger Caravelle, the elbow broke in two. Then my hand lightly brushed against the hard plastic vacuum lines and all 4 of them were brittle and snapped like spaghetti. Does anyone know why they used hard plastic hoses to begin with on this car? How do they connect,,. not with the typical T-fittings, that's for sure. Can I buy the whole friggin' vacuum harness anywhere so I don't have to waste days trying to match up new hoses? Can I substitute regular rubber hoses? I can't believe the car is not driveable now because of a few rotten vacuum hoses. HELP!

The other answer is right on, but neglected one area you asked for help in: you can find a vacuum hose routing diagram in a Chilton's or Petersen's manual.

In 1987 hoses were not hard when new
harden and perish due to heat in engine bay and age

I dont think you can buy hoses as a kit
but worth ringing a plymoth Caravelle parts supplier

you can buy silicone or standard rubber hose

replace one hose at a time and take pictures of the hose joins
don't pull the lot off in one go and have a mess

cheapest way to replace all vacuum hoses is buy the hosing in lengths and sizes required from an auto parts shop

Just follow your exhaust manifold from engine to where it connects to exhaust pipe. It should be right above that, threaded in to exhaust manifold.

The car is idling ruff, it feels like its ready to shut off when i come to a stop.i have to take it out of gear and give it gas so it won't shut off.


These cars had a very common problem with the hose that goes to the PCV valve. The rubber elbows in the hose rot out and create a big vacuum leak. Inspect the hose that goes to the PCV valve and replace any worn parts and your problem will be solved.

P0172 AND P0174 FORD F150 1998


Basically this means that an oxygen sensors
in bank 1 and bank 2 detected a rich condition (too little oxygen in the exhaust).

A code P0172 and P0174 may mean that one or more of the following has happened:
1. The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
2. There could be a vacuum leak.
3. There could be a fuel pressure or delivery problem

Possible solutions include:
Inspect all vacuum and PCV hoses, replace if necessary
Clean the MAF sensor. Consult your service manual for its location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect fuel lines for cracks, leaks, or pinches
Check the fuel pressure at the fuel rail
Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

My 2001 ford escort zx2 has a vacumn leak in the pvc elbow it also was kicking back an engine lean code. it runs but idle runs like it is trying to die when stopped. i've replaced the 02 sensor, plugs,...


for sure its the pcv elbows and hose.
you can only get the part from the dealer and they do not sell the elbows seperatly.you will need to get the whole hose.
they are 30 dollars from the dealer .you get the tube with new elbows on both ends.
its on the driver side under the hood and goes under the thermostat housing.
it is very easy to confuse it with the water heater hose.
the pcv tube connects to the pcv valve then routes back to the bottom of the intake tubes.both elbows are heat burt and torn open.
you will have to replace this new part and for sure all your check engine lights will stop as this air is getting by the mass sensor and not accounting for it in the fuel delivery there for showing a lean mix.a vaccum leak will let unaccounted air in the system and the computer will not deliver fuel for this air .not enough fuel is a lean burn.i just did one on this car 2 days ago.take off the intake tubes so you can reach down in there to take off the old .
let me know if it helps.

Engine codes Po171 Po174 Po401


The vast majotity of Ford vehicles with P0171 and P0174 codes are suffering with a vacuum leak. The biggest culprits are the hoses going to the PCV valve. The rubber deteriorates due to heat and oil fumes. Check the hoses and rubber elbows between the PCV valve and the intake manifold. Pay very close attention to the rubber elbows. They crack on the onside and can be hard to spot.
