Block cleaning.?

[raj]

this isnt about what to use to clean the engine block but more a case of what process?

ive always used a local enginnering firm to chemically clean the c1j cast iron blocks but im now wanting to know what the best method is to clean alloy blocks with built in liners?

i ask because everytime i have a c1j block chem cleaned i have to replace the small alloy core plugs as they dissolve during the process!!!
so obviously i dont want to be using the same method as i wont have an engine to pull back out the chemical tanks:scared:

im not one for cleaning the blocks myself as im abit anal like that and like them perfectly cleeean!

any ideas?

I don't think there's another option if you want it that clean .Replacing core plugs aint the end of the world .If you're that anal you'd do it anyway:p unless it's a Z7U block .....................

OOOOPS .......

I think I misread that but I'm pretty sure you can get the ali block chem cleaned .You will need to replace the plugs ......Or ultrasonic cleaning .

F

The F inline-4 family (for Fonte, French for cast iron) was the successor to the A family. Launched in 1981 on the Renault 9 (http://en.wikipedia.org/wiki/Renault_9) and Renault 11 (http://en.wikipedia.org/wiki/Renault_11), it has been the mainstay of Renault's engine lineup through the early 2000s in a succession of increasingly powerful petrol and Diesel variants in overhead camshaft (http://en.wikipedia.org/wiki/Overhead_camshaft) configurations. It was also Renault's first production four-valve design. It is being replaced by the M engine.


F1N/F2N/F3N: 1721cc
F7P: 1764cc
F3P: 1794cc
F4P: 1794cc (evolution of the F3P, 16V with variable valve control on the inlet camshaft)
F3R/F4R/F7R: 1998cc
F5R: 1998cc (direct fuel injection - IDE - only 2 years in production, used in the Megane Coupé and the Laguna II)
F8Q/F9Q: 1896cc

ah thanks :agree:
ive always been under the impression that they where alloy:confused: i think its because the std colour of the c1j block[when stripped of std paint] is not the same as the f-series blocks which look an alloy colour:confused:
i didnt know iron looks grey/silvery.? i thought it was a very dark greyish colour:confused: :ashamed:

The F engine series information needs to be finessed (by someone appropriately qualified) and placed into the articles section of the website.

if the first 3 digits are followed by the letter S then its a service exchange engine and not the original....

the next 3 numbers denote the model of the engine with extra information if required....ie) designed for use on automatic transmission...

rule of thumb, if the last digit is even its for a manual box, if the last digit is odd its automatic

[Tiny Tim]

I've got an odd digit on mine Paul... looks like a clump of oil and dirt.... very odd indeed. I think its French.

[raj]

interesting info :agree:

can dry liners be removed? im assuming there press fitted:confused:

[paul b]

VERY SPECIALIST REPAIR ....

it can be done Raj, but you cannot buy these parts from renault and do it yourself

is that a "you cant buy them, Period!!"..?

if the parts arent available from reno then where are they available.?
what engine shops would carry out such a job.?

[paul b]

it would be a very special job to remove them , then have new ones made to order and bored/ honed to suit the application...

it really isn't worth it if you can come across another complete engine for the price of 1 cylinder bore liner

I used to do this job at a specialist engine centre in Wolverhampton......back in the 80's it was few hundred in labour....guess that would make it around £800 mark...:eek:
