Exclamation Maruti Suzuki WagonR DIY Stuff. Update: 8 years, half-a-lakh kms and counting

First issue: stock air filter

I have a Jul-02 WagonR VXi nearing 47,000 kms on odo, running stock air filter (purolator) and regularly serviced.

Please see the pics below. Yesterday while DIY engine dusting, I noticed that purolator has turned quite dark and also there was a minor damp oil/greasy patch near the PCV breather hose (?) joining the air filter box. Do not recall seeing this patch before. I do not see any white smoke or power loss and the car runs fine. Oil level (last oil change was done about 6k ago) was also correct and it returns me >14kmpl in city. The car is being used mostly in stop-go traffic for last year (~4k kms) or so.

My questions are as follows:

1) Is the air purolator usable or should I replace it?

Pic b) Bottom view of filter

2) Damp oil patch is serious or is it OK, considering 47k odo? What could have gone wrong?

Pic d) PCV breather connection hose

3) After cleaning the filter with a vacuum cleaner- I feel a bit fast-ish idle (tacho just one step below 1k mark). Should I reset ECU by disconnecting and reconnecting the battery?

Thanks,
-BJ

1) How many kms since last filter change? If more than 10k kms might be a good idea to change. Though you can push it to 20k also if you are running in not so dusty environment.

2) Clean the cover and observe after 1000 kms, if its not really wet its ok. Some amount of oil will evaporate and reach the filter cover.

3) Was the idle reading taken after engine warmed up completely?

Thanks Jaggu for reply. Appreciate it.

IIRC, Maruti recommends 40,000 filter change interval. I might have missed it (need to check) since, my other vehicle (Safari) is dividing my attention these days. Will check the service record. If I change, how prudent it is to go for K&N replacement considering I am approx 47k on ODO and will keep this car for >3 years. Any idea on cost differential OEM vs K&N?

Good suggestion. However, I am curious to know any other member has seen similar oil patch in his/her WagonR?

Probably no. Car was not properly warmed up. It has now settled around 900 RPM.

BJ,

IMHO, it is not worth to go in for the K&N filter. The claimed performance and FE gains are just that - claims.

I wanted to switch to a K&N in my Alto at the 10k kms mark, but on having researched this website, I chose to stick to the OEM filter and recently changed it at my car's 20k kms service though the manual recommended a change only at the 40k kms mark.

Regards,
gpa

Thanks for suggestion gpa. I will stick to oem. How much you paid for your Alto filter? I guess, wagon-r filter too will be similarly priced.

Now thats a claim! There is a difference,though not very significant for a stock replacement filter on a stock car ...

In my case, the Baleno drop-in K&N was costing around 4000/-, and the Maruti replacement filter costs around 400/-. I replace every 15000 km, much earlier than the recommended interval, and so far have only replaced three filters. So economics certainly rules against the K&N.
Personally I also have reservations on the benefits of K&N, but that's another matter entirely and has been discussed thread-bare (!) in other threads here.

Yes plus i think air filter change is every 20k kms. If you dont have much running not worth K&N's.

Smile Mileage increase

Just tanked up yesterday. Noticed, it returned me 413 kms/27 lit (=15.2kmpl) . All city driving with 99% AC. Not sure, the increase is due to the DIY filter cleaning + ECU reset or was my driving sedate.

@bj96- Change your air filter more often, it is not a costly part. Yes, MUL recommends replacement at 40k, which is quite a big interval.

I change air filter in my zen at every 7k service. Doesn't cost much, only Rs.90/- for Purolator brand. The car runs just like new after 1.2 lac km & 7 years of ownership.

Maruti says 20 thousand km intervals for an air filter change in the swift diesel atleast , i anyway changed it on the 15 thousand service as it had totally disintigrated with the material in it looking like it had come from the iraq war.

Ps: when i had the zen petrol the manual said for an airfilter change at the 20 thousand km mark.

Default DIY- clutch squeak fix

Clutch squeak returned back after the "fayhan" deluge few weeks ago. Was looking for the source. WD40 and engine oil on the pedal hinge did not quieten it. Decided to hunt for the source today. Lied on the ground and sneaked under the bonnet. There is a clutch actuating arm at the lowest part of engine where clutch cable joins via a rubber grommet. The mud/slush from the tyre splash accumulates on the actuating arm hinge causing the squeak. This needs to be cleaned and lubricated periodically. More so if driven through rains.

Steps to DIY:

1. Lubricant: "pocket" can of WD 40 and/or some engine oil
2. First spray the lubricant on clutch pedal hinge inside the cabin and check if the squeak goes away? If not, proceed to below steps
3. Lie down on the ground near LHS front wheel well
4. Locate the cable joining the actuating arm via a rubber grommet. See pictures below.

5. Spray lubricant on the cable joint and exposed parts.

6. Surprise yourself with the result

I think, we should avoid greasing this joint as it would attract and settle abrasive dirt/sand on the hinge causing it to wear prematurely. As I do not have the long term experience of greasing this joint, need some expert insight on the suitability of grease here?

Bonus learning:
Looking at the clutch actuating mechanism of WagonR now I am confident that I can replace the clutch cable myself if it breaks down in no-man's land .

You might be having an air-leak bj. Recheck everything carefully.

Thanks for dropping by. Could you please elaborate what air leak are you talking about? WagonR has a old school clutch actuated by a simple cable- no hydraulics there. Are you talking about the air filter? Thread title is misnomer- I will request mods to change it.
