Save my Civic- D14A8- Replace Intake Manifold

Question

Hi all, 

 

I’m in the UK and really happy to find a community here for my UK 5 Door 1998 civic 1.4 LE with engine model D14A8. I’m trying to recommission it as it’s been in the family for over 20 years and had a load of work done jut now.

 

My mechanic has said there is a coolant leak from the plastic intake manifold though. He said the metal coolant pipe connector had corroded and the plastic surround was crumbling. His advise was the only thing we can do is get a another intake manifold to fit or it’s game over.

 

I can’t find one anywhere online for this engine (is it an MB2?), any ideas? Honda main dealer wants £876 for a new plastic one from Belgium but that’s too dear for me. I asked for the part number and he said it’s not company policy to share that.
 

Are there any aftermarket ones that I can buy that would fit this engine? Or can I fit one from a different Honda engine that’s compatible? I looked on eBay without luck and tried to look at the salvage people but nothing is there and all want to sell the whole engine at £300.

 

any ideas as I’m stuck right now.

 

Cheers

Pretty sure all d series Intake manifolds are Interchangable (of course there are some single point Injection models, but the look completely different.)

 

So you could find a aluminium Intake manifold from a z6 for example. And it will bolt on.

Hi all, thank you very much for the replies. I followed up with the eBay supplier Kink43 but they said it wouldn’t fit an MB civic unfortunately. In the end I waited checking on EBay breakers to find someone willing to sell an intake and took that and it’s now fitted without an external leak.

 

thanks for the Lings link Dr Broon, it worked a treat but I think they’ve removed it now sadly. Are there any other parts sites like that please?

 

However I have a new problem as soon as I tried to bring it home as the temperature gauge is flipping between half and 3/4 especially when the AC is on. I’m used to only seeing it around 1/4- half way before we took it off the road.

 

is there a trick to bleeding the coolant system? as originally when the mechanic started doing a service and MOT I asked him to replace the coolant and he said he had trouble bleeding it as the nut on the radiator was siezed.

 

The mechanic said he saw it get hot when idling and he revved it and the gauge went back down to half way. He’s thinking it’s the water pump (he thinks honda fitted plastic impellers? that might have broken off) I’m thinking maybe it’s the thermostat or the radiator.
 

But the thing I’m most worried about is that when we first had the inlet manifold issue, it did heat up just below the red mark on the gauge (no engine management light came on) and I limped it home. There was massive gargling of coolant in the expansion tank and in the radiator itself at the time. 
 

After the inlet manifold was done and the radiator cap was replaced the mechanic said he saw some bubbling in the radiator (not as bad as before) most recently when he was testing it at idle speed. I’m now wondering if the bubbles are from the Head Gasket being gone and was asking him if we can test it before we commit the money on the water pump, thermostat and timing belt. I was even thinking of doing the radiator for good measure as it may have rusted out.

 

What do you think? He said he will try a liquid HG test to see. I’m worried it will be condemned if it’s the HG. Is the liquid test reliable? Any ideas on what to do next please?

Looks like lings are busy updating their website... Another option is https://www.parts-honda.uk/ but I'm not sure they have a reg lookup. 

 

I'm sure there's a thread on here somewhere with loads of advice for bleeding the coolant, but can't find it at the mo.  There's some good stuff here that might help.
