Hi everyone,

Hope u all doing well.
Found out no oil pressure using a manual oil gauge on my Accord '54 plate.
Looks like I need to investigate or replace the oil pump. I don't have the budget to get it done in a garage so I'm entertaining the idea to do it myself. I'm not sure how straight forward would be the job. So I'm writing this post taking my chance if possibly somebody here could share any idea or share a manual or procedure on how to replace the oil pump on my '54 plate accord. Thanks. Have a nice day everyone.
 
Which engine?
 
More likely to have snapped the pump chain. It's a common failure.
 
I already spoke to someone it's a big job. As to lowering the sub frame where it blocks the oil pan removal and removing the timing chain to remove or install the oil pump chain. Making sure the timing is accurately set to top dead center prior to removing the timing chain. Which is the details of this certain procedures is what I'm trying to secure so I have a guide. Like how to set the timing top dead center and lowering the sub frame if there's anything to consider.
Is there really a detailed manual that a garage uses for this certain job?
Thanks for your time Goodluckmomkey.
 
There are a couple of good guids on here. Really a case of suspending the engine so you can remove two of the mounts to remove the rocker box, The sump and the cam chain cover.
One of the problems people seem to have is injector removal, but they came out relatively easily from my '04.

Tdc is marked on the timing gear, you just get it all lined up with the marks before you swap the timing and pump chains.

In a couple of the threads about ti.ong chain replacement I've put links to the online manuals i uswd when i did the chains on my CDTI.
 
Thanks for all your time. I'll have a look on all this link you all share.
Really much apreciated. Have a good evening to all of u.
 
No probs. Manners get you everywhere.
 
Dani is a good bloke, I know him personally. Please extend whatever help you can to him guys.

Cheers

I had to replace both my chains. Lowering the subframe isn't really a big deal and neither is getting the timing right... but, as the links provided by freddofrog show, there are also other hurdles along the way! I had a battle getting the crank pulley bolt undone, while others struggle with injector removal (I didn't). I also spent a lot of time getting a previously rounded-off bolt off the a/c compressor. You will need an engine hoist, but I managed to avoid buying any special tools to do the job.

I agree with Goodluckmonkey that the lower chain has broken, rather than the pump having failed. You were lucky that the broken pump chain didn't then cause the camchain to break and wreck the engine. But are you really sure that the engine hasn't suffered and damage as a result of having no oil pressure? I know it's hard to tell, but unless you switched it off immediately when the oil pressure warning light came on then I think it may not be worth wasting time and effort fixing it...

An oil pump is a pretty solid piece of kit that generally gives lots of warning if it wears out, and generally only fails acutely if something else catastrophic occurs inside the engine. If your oil filter and sump aren't full of metal shavings, and you haven't been suffering a gradual increase in oil pressure warnings, the most straightforward explanation is that nothing is driving the oil pump.

Oil pumps generally last the life of the engine. There are ***ociated parts such as relief valves and O rings that can play up, but even that is rare.

So far, few of my mates listened to the engine after I changed my turbo recently and they said no metal to metal sounding like on the engine as we tested starting the car on idle.
Car starts alright and idles well at the moment.
But before I will finally start doing the job I will check the oil I just recently drain and the oil filter for presence of metal shavings suggested by Richard.
Thanks for all the concerns and tips. Every little helps everyone. Have a nice to all.

So, just to double check, is the oil pressure light on permanently?
 
I change Oil pressure switch as well from Honda. Just thinking aloud, what else could cause a no oil pressure aside from anything related with the oil pump?[emoji848]

A few electrical issues could cause a permanent oil pressure warning light, but if you've manually checked and can't see evidence of oil pressure then it's either the pump itself or the chain..

I also would refrain from running the engine when you know there is an oil pressure problem present.
