what engine is please

26th February 2014, 08:58

just bought car and wanted to know what engine it was, either early or later model, what bhp etc..

thanks

also i have a strange thing happening at first start up of the day...

when i first get into the car to start it after stood all night, it starts then dies, then starts again then dies, but on the 3rd/4th attempt and a little bit of throttle its okay and wont do it again all day??

any clues??

Late Vtr, 2001 onwards 98bhp, three plug ecu, two lambda!

Its always a good start to give the car a full service!

26th February 2014, 09:37

thanks

so is this the better or not? lol

any clues to my starting problems?

thanks

26th February 2014, 09:39

its the later vtr engine so yes, better than the previous. As quick said, give the car a full service then see if the problem carries on.

26th February 2014, 09:41

okay will do thanks, could it be a plug problem?

better than the previous what? blacktop?

26th February 2014, 09:47

what are the better engines? the 90 bhp one single ecu or the 98 bhp 3 point ecu?

26th February 2014, 09:59

Ive been told the old 90bhp black top is easier to tune than the new one.. whether this guy was being truthful or not I dunno.

Depends what you want to do, out of the box then the 3 plug silvertop 98bhp unit is the better one to go for.
There are two 90bhp units, a black top and silver top 90bhp the latter being the worst. However with the black top engine, it uses normal rockers not roller rockers like the silver top does which gives you more options for tuning as they can handle a higher rev limit due to harder springs.
the 98bhp has a different port spacing on the head for the inlet manifold to fit as opposed to the 90bhp units so this can cause a problem if you wish to swap to throttle bodies or a rallye inlet.
Also the 98bhp has a different oil filter setup, a cat in the manifold and an extra lambda sensor which can both hinder you when swapping manifolds to an uprated version due to the higher availablity of earlier 90bhp type after market manifolds.

If you've got a 90bhp unit car, then you can quite easily put in a rallye/xsi unit like I have done without so many changes as opposed to a 98bhp unit.

Black top engines are stronger engines iirc.

thanks for all advice, but back to the start problem, surly if it was dowb to a service then it would be like that through out the day? but it is only in the mornings, first time start up...

cheers

26th February 2014, 11:43

could be numerous issues, best to get any fault codes read on it.
Try removing the ICV and clean it too

26th February 2014, 14:56

ICV
coolant temperature sensor (for the ecu)

if you start it and lift the revs immediately does it cure the problem?

26th February 2014, 15:35

hi, if i lift the revs its okay until i idle again and then it dies, but after a few attempts its fine i can shut it off and start it again and it sits at idle fine and goes like that throughout the day...

until the next morning lol

26th February 2014, 15:38

my first stop would be a coolant temperature sensor for the ecu... its on the right hand side of the head iirc there is 2 and i cant remember what one is what, someone will clarify as the other is for the dash...

26th February 2014, 15:40

thanks, is this cleanable or just replace?

thanks

iirc?

26th February 2014, 15:46

iirc (If I Remember Correctly)

and its a replacement thing mate, there not that expensive, i got mine off ebay for £5.30 delivered or something like that, euro car parts would be a good bet and probably faster getting it to you as well...

26th February 2014, 15:51

nice one mate, ill order one asap, if its not this tho? any more suggestions?

26th February 2014, 16:06

Green is usually the one of the ECU, a light blue for the gauge I think but that said both mine were a light blue colour originally but ive changed them now. Its easy to tell though in regards towhich one you pull out if it doesnt affect the dash gauge when the car is running then its the ecu one!

26th February 2014, 16:15

^^ thats an easy way to sort it out

26th February 2014, 16:23

I got a blacktop engine in my 1998 vtr and they are robust as fxxk. i accidently was driving around with close to no oil (no oil showed on the dipstick) for about a week and its still going, i also shifted into 1st accidently doing about 25mph, revved its tits off but still it drives!

28th February 2014, 15:34

have you tried taking the car to garage and get them to check to see if there are any error's flagging up? also try disconnecting battery over night this resets the ecu might work.

hi mate, i have a ODB 2 fault reader and nothing has come up, all sensors seem to be ready and working okay??

im looking into the fact of the icv valve? but i dont know quite how to get it off on my engine as it is botled to another big part lol

hi mate, so to replace this is it a bolt and will any coolant come out lol?

cheers

28th February 2014, 15:55

Yeah its in direct contact with coolant so yes some will leak, you may need to rebleed the system after doing so too. it will undo with a ring spanner

28th February 2014, 16:48

^^ as above... But you WILL need to bleed the system... Its easy tbh

28th February 2014, 16:50

Ive gotten away with it in the past, if you are quick and swap it fast - dont let too much coolant drain out so a big air lock cant form. Then top up

1st March 2014, 10:28

but if i need to bleed it how and where? is there a bleed nipple or screw some where, ive seen one on top of the rad on the left hand side...

also maybe wrong place to ask this but on my engine how do it take out the icv? as i looked at the guide to clean it but its not my enegine, but it looks like my throttle body is connected to something at the back? maybe injectors part? idk but any info would be greaaat!

1st March 2014, 20:06

can any1 help me out ??? i have the 3 plug ecu 98bhp engine and have just bought a piper 4-1 manifold but it only has one screw bolt for 1 sensor, what do i do about the other1 thanks and sorry for poaching your thread lol

so on the right hand side, of the rocker there is two sensors?
here is mine, but the blue one is into the coolant system and the other one looks like it is just there and connected to the lambda?? thats all i see

can you claify on this, or is there any guides to show you how to bleed system??

thanks

2nd March 2014, 22:56

there should be 2 sensors the blue one you see and one round the back. get the engine warm and pull one off and look at the interior gauge. you want the other one to what makes the interior dash gauge go funny...

yeah there are guides on here...

tbh the way ive always done mine is top the coolant and to the left of the intake manifold youll see what looks like a tyre valve cap, undo this and pour water in until it runs out of the hole, tighten and move onto the bleed bolt on the thermostat housing where the temperature sensors are, repeat until bled and then do the same with the one on the top of the rad

so am im looking down at the engine i see a tyre valve thing but its on the right and i think its the fuel rail? with like a pressure release valve inside that..

but ill have alook on the left later today.. and there is a plastic type screw nut thing on the top right is this what you mean? thanks

3rd March 2014, 13:45

Ill take a picture when i get to the workshop and show you what i mean

thanks bud
