    I have a 1992 200te with about 177000 miles on the clock and I am planning on giving it a quick service this weekend from the looks of it it has not had one for at least 2 years. It has a noisy/tapping lifter on start up and for about 5-10mins after. So I was thinking of using an engine flush to try and solve this problem, is this a big NO NO? and should I just live with it.

    Give it a quick flush by all means, it cannot do any harm, follow that up with a fill of cheap oil and change it all after say 500 to 1k miles to a good quality oil

    Indeed, a good flush, carried out as per the directions on the product, can do no harm.

    Once you fill with a good quality oil, see if you can find some "valve lifter treatment". In SA, we have a product by Wynn's, and it seriously is one of the very few "mechanic in a bottle" products I recommend.

    I've always been wary of using engine flush after a mate used it on a CVH escort many years ago. Afterwards, he put new oil in, but when he started it, the oil light stayed on. In the end, he had to take the sump off to manually prime the oil pump. I wouldn't risk it, and would rather just do an oil change with some decent oil. If it rattles, why not just change it sooner, or if that doesn't work, replace the faulty hydraulic lifter ?

    You could try flushing it, but there are problems with doing so sometimes as it dislodges debris and this can cause damage by lodging in other areas. So do it with caution. Landrover do use Forte Engine flush as a treatment, I've also used it regularly and havent experienced problems.

    TBH I've never understood engine flushing, I think it's a product & process dreamt up by automotive chemical makers to generate work & ££ for garages.

    If your car has been properly serviced with decent oil then there will be no need as it will already be clean.

    If your car has been under serviced, neglected or run on the wrong oil you risk dislodging crap & blocking oil passageways. In a case with these conditions I'd let sleeping dogs lie & just change the oil & filter, using quality parts.

    I flush customers cars regularly. Diesel on every large service. Never ever had an issue

    Sorry for the slow update. Should have checked to see if the sump bolt was stuck/rounded before putting the flush in but I didnt so a few days of driving with flush ensued, only about 6 miles. Garage loosened bolt and all is now good. Oil/ filter change and the wynns lifter fluid has solved my noisy engine
