Valvoline if using low viscositie like 0-20

nice vid
whats the total cost of 1kr build these days ? parts + labors + fluids etc

[rajaatta]

Total was 57k to 70k on this engine all things invluding labor parts and lubes.

I have heard from different mechanics that Passo and Vitz engine should be changed instead of overhaul because they are made up of silver. Sunnel Munj also said in his Vitz user review that 1 KR-FE is a disposable engine. Since you are again overhauling this engine, what are your comments regarding it?

Good Job!

[rajaatta]

All over the world quality tecnicians always rebuild the engine if the engine is desighned disposible then car manufacturers would face a lot of cases than because new engines costs the 2/3rd of whole vehicle price.

[rajaatta]

It was my 129 th rebuild the video was just for refference due to shortage of time i could not explain every bit in detail wriiten form so composed the video. 1kr and every running engine of aluminum is rebuildable our mechanics lavks the skills plus they pit all of the responsibility on machining shops who in return have desi calcuulations for redoing engines hence results in total failure.

Brother where have ypu been. Its long time

[SER_GTR]

just busy with life so not much time .... i would like you to put more details on boring honing machining and valve job seals so people get aware that rebuild is also an option not just shoving and swapping motors...some DIY's pictorial and video tutorial will help many people

its just a hard way of doing it but on long run its reliable keeping cars original block and value!

[rajaatta]

Yes its true life gets busy . I had tons of videos the only problem i am facing is also time trying my best to make detailed video on how to perform it. But there are cons and pros one of our fellow member asked me about the procedure i explained in detail but when he was diy ing his engine rebuilt he get it macheined from normal engine kharadias and end result was on first start it seized then he opened up the engine and sended to us we rebuilded it again and now its running fine. Thats the tragedy.

@rajaatta sir can we overhaul suzuki 660cc K6A with new parts?

[rajaatta]

Yes if the parts are available

Keep The Tips Video So People Can Avoid Doing That Or Atleast Get It Done correctly From Machinist

Yes true. I always prefer rebuilds over swaps. Nobody knows the actual condition of a 2nd hand engine.

[speedster_101]

In the beginning of the video you said that you have already conducted the compression test and values were 200 plus. Were they not good enough? What should be the ideal values?

[rajaatta]

The normal engine compression is 175 psi for a healthy engine. Any thing more than that indiactes that the residues are forming up in combistion chambers which will in future detoriate the piston rings.

200psi compression is fine unless there is no smoke present with it.
Only assesing the engine on the basis of compression can easily misguide the whole diagnostic procedure so compression along with smoke test is nessacary to better understand whats going on inside the engine.
So thumb rule for new engine is
1: perform compresion any thing beyond 175psi indiactes carbon build up in cc which can lead to octane knock that ends in engine piston rong failure.

2: if compression is fine you must perform smoke test because compression can easily misguide so smoke test reveal the actual situation.

3: high compression along with smoke indiactes that bore has detoriated and if knock is also found along woth it. Its rod knock or piston slap commonly occurs in detoriated 1KR-FE and 2SZ-FE.

Yes true. I always prefer rebuilds over swaps. Nobody knows the actual condition of a 2nd hand engine.

My two swapped engine are in still in use from 8+ years. Market is full of junk if you know what you are buying swaps can be equally successful.... No doubt rebuild is always the 1st option if engine is in the condition of successful rebuild. Attaching pic of my 8 year old swapped engine.
