Disaster on the way home from the meet :(
 

Did a little bit of a high speed run on the way back from the meet yesterday, no problems, then on slowing down noticed a slight tapping which grew continously worse. Strangely enough if i kept the car on boost it seemed to go, so i decided to nurse it home i was was almost there, and other than a knock warning on the Power FC, there where no dash warning lights illuminated (such as oil pressure etc). Had to stop at 1 set of lights and the car cut out then wouldn't idle, i managed to get it started and pull straight off as i was only half a mile from home by now. As i drove the car the last half mile it was knocking its little heart out but strangely enough when i pulled on my drive it was happy to idle although still knocking. Any ideas peeps, me and a couple of mates have discussed it and they seem to think its either the oil pump has failed or its holed a piston or something. What do you guys think and whats the options for what to do and where to take it? The car is an MY93 wrx JDM Import and i live in Bridgend. I suppose i'm not too upset about it as the car has done over 100,000 miles and its been tuned by a well known tuner to about 300bhp so thats the risk you take tuning older engines. :rolleyes: :( Prob is she's not just my play thing shes my everyday work horse so i need to get it done ASAP.

Really sorry to hear it mate. It does sound like it could be the oil pump but im no expert.

dodgy MAF maybe?

:( Oh dear, hope you get it sorted soon.

Hope it's not too serious:(

Cheers guys, but its gonna be a bottom end job. Whats the best thing to do, get mine rebuilt or buy one already done with uprated components? Don't wanna get a second hand 1 as most of the expense is gonna be labour anyways so may as well get it done properly first time. Seems the big end bearing has gone, was thinking new set of pistons, group A head gasket new oil pump to be on the safe side. Who would you recommend, Andy from Ace motorsport perhaps? I've heard good things about him. Any suggestions? More gutted about being carless than anything. :(

The oil pump looks the most guilty suspect, but innocent until proven guilty.

How bad is the knock? And is it coming from a certain area on the engine?

Ye its bad and its coming from the bottom end. I suspect its the big end bearing. Looks like a bottom end rebuild, but need to know if its gonna be cheaper to rebuild my existing bottom end with uprated parts or just buy a new one from a motorsport company already built with uprated parts. Don't want anything for massive power, just something that will run about 350bhp all day, something rated to about 400bhp, so i've got a safety margin. I can't really complain, she's done over 100k's and is used everyday.

It all depends finances and how quick you want your baby back:thumb:

Oh dear another scoob off the road, I want mine back but CVC said they cant look at it until Monday, and they've had it since Thursday :cry:

Hope yours is up and running again soon.

What about something off the shelf from API? cue David.

The return valve in the standard oil pump is not up to the job, On the new engine replace it with rcm one they are the best.

Ye good idea, i'll give him a call and see what he suggests. This may speed things up a bit too, thanx :thumb:

Call me Monday, we can sort you out with something either standard or uprated.

Tough luck on breaking it though.

David APi

Cheers for the reply David, i'll give you a bell monday afternoon. :thumb:

As already said, David is your man, When mine goes thats where I'll be taking mine, 103K and counting!!!!

This may be worth a look if your considering going 2.5:
2.5L Closed Deck Forged Short Block Impreza 92-00 Flat4online.co.uk Subaru Impreza Mitsubishi Evolution EVO Walbro Fuel Pumps Injectors Intercoolers

NOT on a 93 WRX, it'll cost too much to get it running right.

David

Looks like API are going to be doing the work, very happy with their prices and time frames. Full rebuild on its way. :luxhello: Big thanx to David for ringing me earlier :thumb:
Taylor.

Where do you get that idea from?

David are you say the standard oil pump is fine?? or just the description of why it's not up to the job is wrong???

The original oil pump is a fine piece of kit, that is maligned unnecessarily, in my opinion.

In well over 1000 engine rebuilds we have only ever had to buy 5 new pumps. And those only due to debris damage on the gear faces, nothing to do with sticking relief valves.

We simply take the original to pieces and clean it thoroughly, polish the reflief valve to a high shine to deburr it and off they go again.

They make excellent pressure as-is and we don't have any worries about what and how we do it.

The RCM one is also a fine bit of kit, if it makes you happier to buy that, then feel free. We have only ever fitted 3 or 4 of those and that is usually because the customer has called me to discuss before spending hard earned. OR has bought it before he gets to me.

David APi

Cool, i was planning to replacing mine with a RCM one when i get a new engine, but perhaps i won't bother now, save a bit of cash :)

keep the tips comin david:thumb:

Had mine done at APi, David and the boys will look after you:thumb:

Cheers guys, hoping to get the car booked in with API for a full rebuild ASAP.
Taylor. :)

Would this be any good

Not on an early WRX, no it wouldn't.

Tips? Tips? nobody ever gives me tips. Not even for the 3 legged donkey in the 2.30 at Ascot.
